Rubber Washer Rings


A washer is a rectangular-sectioned rubber ring. On the market, square cuttings, lathe cuts, as well as square-rings washers all have common names. The size standard parameters including the groove design of washers are identical to those of O-Ring AS 568, however owing to the product's basic configuration, customization is fairly straightforward. In comparison to O-Rings, washers are much more resistant to high-pressure situations and have a longer service life. Washers are frequently used in lieu of O-Rings.


Rubber Washer Rings: Characteristics & Advantages

Rubber washers may be utilized in a variety of applications, including static seals, piston seals, and rod seals, in addition to static sealing. Comparing rubber washers to O-rings, the rubber washers' location of the mold parting line may be modified as per the sealing surface, hence the need for no burrs can be met while maintaining tighter dimensional tolerances.

The filling frequency of the seal in the groove is increased more effectively when using rubber washers as opposed to O-rings. Additionally, the probability of leakage induced by the seal moving or twisting in the groove is reduced more effectively with rubber washers.

Frequently Asked Questions

Washer rings are used to stop a passage via which a liquid or gas may otherwise escape. The o ring is inserted into a groove to hold it in place before being crushed between two surfaces.

An o-ring is typically (but not necessarily) spherical in shape and formed of a compressible substance such as rubber, neoprene, silicon, and so on. A washer has a square or rectangular form and is often composed of a tougher material such as brass, copper, aluminum, or steel.

Washers and gaskets are interchangeable. Washers distribute the weight of a threaded fastener, while gaskets prevent leakage between mating surfaces. Most washers will not prevent fluids or gasses from leaking; instead, they will disperse the weight of the fastener with which they are used.

PolyTetraFluoroEthylene (PTFE) Rings


Polytetrafluoroethylene (PTFE) is a thermoplastic fluoropolymer. PTFE has a low friction coefficient, great insulating qualities, and is chemically inert to the majority of chemicals. Also, it is resistant to elevated temperatures and is well-known for its anti-stick characteristics.

Moreover, PTFE is a high-molecular-weight polymer that is one of the most flexible plastic materials available. It is used in a wide variety of goods for uses that other materials are not suitable for. These rings are well-known for their great resistance to heat, chemical agents, and solvents, as well as their anti-adhesiveness, dielectric characteristics, low friction coefficient, plus non-toxicity.

Tensile and compressive qualities are highly dependent on the manufacturing procedures and the polymer utilized. PTFE, on the other hand, may be utilized constantly at temperatures up to 250°C (482°F) while retaining some compressive plasticity at absolute zero.


The Extensive Temperature Range Of PTFE

PTFE's broad temperature range (-1,000F to +4,000F), nonreactivity, resistance to water, and low friction qualities make it a good material for manufacturing O-rings for a number of applications. These characteristics make PTFE O-rings an excellent option for applications requiring weather resistance, as well as electrical and thermal insulation.

Due to its thickness, PTFE O-rings are not "melt-formed" but rather squeezed and sintered to get the desired shape.


Advantages of PTFE Rings


Resistance to corrosion

Materials that are incompatible with standard rubber compounds, as well as caustic or corrosive substances, may necessitate the use of PTFE.

Due to its resistance to almost all industrial solvents, PTFE is among the most corrosion-resistant polymers available in all industries. And if chemical assault compromises the durability of rubber composites, PTFE may be the answer.


Extensive shelf life

PTFE may also be used in applications needing long life or longer service periods in harsh conditions.

While certain elastomers may survive for a short period of time or in intermittent contact, deterioration over time may cause difficulties years later, while PTFE's resistant qualities will persist forever.


Capabilities across a broad temperature range

The temperature range of PTFE is also far greater than that of most elastomers, ranging from -325°F to +500°F.

Usage in cryogenics or high-temperature environments like ovens or combustion processes may likewise exclude the use of any elastomer compound, once again favoring PTFE.

Extremely low temperatures cause the majority of rubber compounds to stiffen to the point where they lose their elastomeric capabilities. This, paired with the material's contraction, may result in the material ceasing to operate effectively as a seal.

In comparison, PTFE maintains its flexural and pliability qualities at cryogenic temperatures.


Why You Should Choose Flextron’s PTFE Rings

At Flextron, we offer high-quality and industry-grade PTFE rings, which come with the following benefits:

  • Infinite Shelf Life: Because PTFE does not decay with age and therefore is unharmed by UV radiation, age management is not usually required.
  • Our PTFE does not enlarge as a result of moisture absorption, and it is not prone to explosive decompression.
  • Virgin PTFE complies with FDA regulations.
  • Our PTFE has exceptional electrical qualities, including dielectric strength as well as electrical resistance.

Frequently Asked Questions

PTFE is a thermoplastic polymer with a slick surface, a high melting point, and resistance to "attack" by almost all chemicals.

Yes, due to the following reasons:

  • PTFE does not expand when exposed to moisture.
  • The explosive decompression of PTFE is not possible.
  • The FDA has approved virgin PTFE.
  • PTFE has exceptional electrical qualities, including dielectric strength and electrical resistance.

Unirradiated PTFE debris may be recycled into a variety of different products, such as rods, tubes, and sheets, by pulverization followed by heat treatments identical to those performed on virgin PTFE. Technically, recycled PTFE is known as "Reprocessed" or "Repro" PTFE, or mechanical grade PTFE.

 

Black Rubber Gate Valve


Gate valves are extensively utilized in a variety of applications and therefore are suitable for installation both above- and below-ground. Not least for subterranean installations, it is essential to choose the appropriate valve type to prevent incurring significant replacement expenses.

Gate valves are available in completely open or closed configurations. They are utilized as isolation valves in pipelines and should never be used as control or control valves. A gate valve is operated by spinning the stem clockwise to shut (CTC) or clockwise to open (CTO). When the valve stem is employed, the gate travels upward or downward along the stem's threaded portion.


Applications

Gate valves are utilized in a variety of applications.

When little pressure drop and a free bore are required, gate valves are frequently employed. When completely opened, a conventional gate valve has really no blockage in the flow line, resulting in very minimal pressure loss, which enables the deployment of a pipe-cleaning pig. A gate valve is a multi turn valve, which implies that it is operated by a threaded stem. Due to the actuality that the valve must be turned numerous times from open to closed, the sluggish action also eliminates water hammer effects.


Parallel Vs. Wedge-shaped Gate Valves

Parallel and wedge-shaped gate valves are the 2 primary types. Parallel gate valves employ a flat gate across two parallel seats, as well as a typical design is the knife gate valve, which has a sharp bottom edge. 2 inclined seats, as well as a slightly misaligned inclined gate, are used in the wedge-shaped gate valves.


Metal Seat Vs. Resilient Seat Gate Valves

Prior to the introduction of the robust seated gate valve, gate valves with a metallic seated wedge were frequently employed. A depression at the valve bottom is required to accommodate the cone-shaped wedge design with angular sealing mechanisms of a metal seated wedge. Sand and stones are embedded in the bore at this point.

Regardless of how completely the pipe system is cleansed during construction or maintenance, it will never be fully free of contaminants. Thus, any metal wedge's capacity to be drop-tight will gradually deteriorate.

A robust seated gate valve features a simple valve bottom, which allows sand and stones to travel freely through the valve. If contaminants flow through the valve when it shuts, the rubber face will seal around the pollutants. As the valve shuts, a high-quality rubber compound collects the contaminants, which are washed out when the valve is opened once more. The rubber covering will revert to its previous form, ensuring a completely leak-proof seal.


Ascending Stems Vs. Non-rising Stem Gate Valves

Rising stems are connected to the gate and rise and fall in lockstep with the operation of the valve, giving a visible indication of the valve opening and allowing for grease application. A nut revolves around the threaded stem, therefore repositioning it. This kind is only appropriate for installation above ground.

Non-rising stems are inserted into the gate as well as rotated to cause the wedge within the valve to rise and fall. They occupy less vertical space than other valve types because the stem is contained inside the valve body.

At Flextron, we produce gate valves that have a factory-installed indication on the stem's upper end to show the valve's position. Gate valves having non-rising stems are appropriate for installation both above and below ground. So, contact our experts for more information today!


Frequently Asked Questions

How does a Rubber Lined Valve function? The regulating medium of air pressure or water is utilized between the valve body and the sleeve to provide 100% closure of the rubber lined valve (even against big abrasive particles). When this pressure is exhausted, the valve quickly opens.

Gate valves are classified into two types: parallel and wedge-shaped. A flat gate is used between two parallel seats in a parallel gate valve, and a typical form is the knife gate valve, which has a sharp edge on the bottom of the gate.

For opening/closing a gate valve, the AWWA operating formula is 3 times the nominal valve size + 2 or 3 turns of the working nut. A 6-inch gate valve, for example, would take 6 x 3 = 18 spins plus 2 or 3 turns, for a total of 20 to 21 turns.

 

Anti Vibration Mounting Pads


Anti-vibration attachments are rubber-to-metal components that isolate vibrations from cars, equipment, or machinery. This oscillation, or back-and-forth movement, may result in excessive noise and wear, endangering human health and safety and resulting in mechanical failure. Vibration mounts, also known as isolation mounts, are composed of a molded rubber component permanently connected to a metal body. Certain anti-vibration rubber mounts have a metal rod-like fastening. Others are specifically intended to hold one.

Flextron manufactures vibration mounts for original equipment manufacturers (OEMs) and third-party suppliers in areas like heavy machinery, aerospace, medicinal, industrial equipment, and generator sets (gensets). We have a network of strategically positioned warehouses and thus have the capability of fabricating gaskets and distributing materials. We can offer you all of the rubber, plastic, plus rubber-to-metal components you need via our kitting and bespoke packaging services.


Vibration Isolation and Mounting Materials

Rubber is used to dampen vibrations since its shear modulus is greater than that of other materials. Rubber is less prone to become permanently deformed when it is shear strained (i.e., strained parallel to its cross-section). Rubber is however elastic and resistant to the heat generated when molecular vibrations transmit kinetic energy. Although most typical vibration mounts are made of natural rubber, specialized products may be made of silicone, EPDM, NR, or NBR to resist particular weather conditions.

Typically, an anti-vibration mounting is constructed of steel, a robust and heat-resistant material that is less prone to distort or bend under strain. Steel is employed in the rubber-bonded body as well as any bolts, nuts, washer, or plates. Threaded fasteners are employed because vibrations may cause smooth-sided fasteners to loosen. Screws and nuts may be cold-formed or soldered, and corrosion resistance can be achieved by zinc plating or bluing. Stainless steel might well be needed for culinary or medical purposes.


Bell-Shaped Anti-Vibration Mounts

Vibration mounts in the shape of a bell, or machine bolts, are a diverse range of items that mimic a doorbell as well as a school bell. The bell might have had an uncovered metal surface that has been treated to prevent corrosion, or it may have rubber-to-metal bonding. The upper portion is wide and flat, with a rigidity that prevents motion in all horizontal plane directions. The rubber's kind and durometer are determined by the application.

The majority of bell-type anti-vibration mounts lack a threaded fastening. Rather from that, they feature a metal plate containing 2 or 4 bolt holes. Interlocking metal components or a safety lock may offer fail-safe protection in mobile applications. Certain goods have drain-like tubes that aid in the removal of impurities and safeguard the rubber. Additionally, this category comprises fixed machine mounts including bumper mounts.


Applications for Anti-Vibration Mounts

Rubber anti-vibration mounts are used in a wide variety of industries. Several frequent uses include the following:

  • Heavy equipment (on-road and off-road)
  • Industrial and construction machinery
  • Diesel engines
  • Generator sets
  • Pumps
  • Instruments
  • HVAC systems

Flextron can assist you in selecting the appropriate vibration mount for particular applications and can provide on-time shipments based on your sales estimates.


Frequently Asked Questions

The bigger the overall weight, the larger the mountings or, more mountings are required to decrease machine vibrations. Determine the weight of each mounting. Remember that the weight of the apparatus may not be uniformly distributed.

Depending on the kind, most anti-vibration mounts are constructed of heavy-duty rubber or a combination of rubber and another material. The mount has been attached to the equipment. When the machine is utilized, the mounts absorb and dampen vibrations, lowering vibration and noise production significantly.

Even outside of industrial usage, they are fairly typical purchases — many families employ anti vibration pads under chair legs and tables to preserve hardwood floors, and beneath washing machines to minimize noise and "walking."

 

Flexible Rubber Spider Couplings


A jaw coupling is a kind of transmitting power coupling that is also useful for motion control applications, such as motors. It joins two shafts while reducing vibration and adjusting for parallelism, angular misalignment, and axial misalignment.

Jaw couplings are composed of three components: two metal hubs sandwiching an elastomer insert referred to as a "spider." The three components connect together press-fit, as well as a metal jaw from every hub interacts with the spider's lobes. Torque is delivered via compression through the elastomer spider.

Spiders are fail-safe, which implies that even if the elastomer fails, the hubs' teeth will join, and also the coupling will proceed to transfer torque without causing damage to the equipment. Failure may be clarified to a variety of factors, including misalignment, hub failure, severe temperature, vibration, excessive torque, and chemical exposure.


Spider Coupling Materials

Spiders are made of a variety of materials, with rubber being the most common.

The spider's material is selected to accommodate a multitude of criteria, including its capacity to manage vibration, compensate for misalignment, and operate within a certain range of temperature. Additionally, the speed of the equipment and the chemical conditions must be considered. There are 4 materials available, with rubber being the most popular:


Nitrile butadiene rubber (NBR)

Buna N, as it is sometimes referred to, is the most cost-effective and commonly utilized spider substance. It is quite similar to natural rubber in terms of durability and elasticity. Additionally, it is resistant to oil, hydraulic fluid, and the majority of chemicals.

Rubber has the best vibration dampening qualities, as well as strong compression set resilience and elongation. It operates between 240 and 212 degrees Fahrenheit.


Urethane

Urethane has a higher torque capability than NBR and is resistant to chemicals and oils. However, it is less effective at controlling vibration and has a limited working spectrum of 230 to 160 degrees F. Additionally, it is up to twice the price as NBR.


Hytrel

Hytrel is resilient to oils and chemicals and carries three times the torque of NBR at high working temperatures (260 to 250 F). However, at 3 times the cost of rubber, it has poor angular displacement ratings and damping capacity.


Bronze

These metal spiders soaked with oil are utilized in applications requiring low speeds, thrust force, and increased temperature resistance. They have a limited capacity for misalignment and no damping capacity. They cost at least 3 times as much as spiders manufactured by NBR.


Spider Coupling Designs

Rubber spiders are available in a number of designs, some of which are mentioned below:


Spider with a solid center

By far the most often utilized type, particularly where the spacing between both the ends of the driving as well as driven shafts is sufficient to support the spider thickness.


Open-center type (OCT) spider

These spiders are most effective when the shaft ends are closer together. Due to the fact that the spider's legs are connected by such a tiny segment of material, they have limited support, and speeds are restricted to 1,750 rpm for NBR spiders.


Snap-wrap spider

The spider legs are linked around the circumference of the coupling in this form, allowing them to be installed without interfering with the hub alignment. One disadvantage: they are twice as expensive as the previous two.


Load cushions

Load cushions are secured in place with a collar and are easily removed and replaced. They are available for a limited number of collar models.
