Genuine Viton® Sheet -
Gasketing perfect for gasket cutting, flat seals, door seals, Industrial applications. Standards are in stock or custom manufactured to your specifications. Viton® is a high tech. elastomer designed for extreme heat, oil and chemical resistance. Viton® resists aliphalactic aromatic and halogenated hydrocarbons, concentrated acids, alkalis, animal and vegetable oils.
Viton® is not generally resistant to ketones, low molecular weight esters (such as ethyl acetate), or nitro containing compounds. products are not usually serviceable below - 15 degrees F.

While there are substitues that will often perform, specifying the most recognized name in FKM material is an inexpensive form of insurance. Insurance that you will get what you pay for. Not all FKM's are equivalent.
Specify the Grade you need:
Specifications that are insufficient, inaccurate or that allow substitutions open the door to quality and performance problems. When you specify DuPont Performance Elastomers' Viton®, the most specified fluoroelastomer worldwide, you can enhance your products' performance by ordering the specific type of Viton® that has been tailored for your application needs.
Viton® was introduced in 1958 and scientists and engineers have relied on DuPont and now DuPont Performance Elastomers Viton® for its superior performance and unique properties ever since. However, DuPont Performance Elastomers is not the only company that manufactures FKM products. Many people in the industry incorrectly refer to any and all FKM elastomers as Viton®. As a result, you could end up with sealing products that are not the type of Viton® you need, let alone made of 100% virgin DuPont Performance Elastomers Viton®. Products not made from DuPont Performance Elastomers Viton® may fall short of the expected performance levels afforded by the stringent quality standards DuPont Performance Elastomers has set for Viton®, which is manufactured at ISO 9002 registered facilities worldwide.
Q. What is FKM?
A. FKM is the ASTM designation for the fluoroelastomer category. It is not a mark of quality. Not all FKMs are equivalent, and some may fall short on desired performance.
Q. What does the "Made With Genuine Viton®" seal mean?
A. It means the part has been manufactured and distributed in accordance with DuPont Performance Elastomers' guidelines. Only parts made with 100% virgin Viton® as the sole elastomeric component are labeled with this seal.
To ensure that you always receive the highest quality FKM products available, insist on 100% virgin DuPont Performance Elastomers Viton® and look for the "Made With Genuine Viton®" seal.

When it comes to cutting gaskets there are several ways to get the job done. Traditional "clicker presses" are great for larger quantity jobs and have been the standard in the industry for years. The biggest down side to using clicker presses is tooling must be made to produce a gasket. Just as CNC lathes revolutionized the machining industry, laser cutters, routers and water jet are all computer controled ways of cutting a gasket with out the need for tooling or dies.

Fills the space between two objects, generally to prevent leakage between the two objects while under compression. Cut Gaskets saves money by allowing less precise mating surfaces on machine parts which can use Cut Gaskets to fill irregularities. Gaskets are commonly produced by cutting from sheet Cut Gaskets, such as gasket paper (beater addition), Non-asbestos, Rubber, EPDM, Nitrile, Buna, Neoprene, Flexible Graphite, Grafoil®, Aflas, Kalrez®, Viton®, Silicone, Metal, Mica, Felt or a plastic polymer such as (PTFE), Peek, Urethane, or Ethylene Propylene (EP). In the past, the Cut Gaskets selected for specific applications may contain have contained asbestos.
Today's sealing products manufacturer's in the United States no longer produce or offer any asbestos containing products. Cut Gaskets containing asbestos have been claimed to have caused Asbestosis. Of course it would take the grinding of Cut Gaskets to release the fibers and then the breathing in of those fibers....possible but in the real world this would be rare. Wetting or oiling a gasket before grinding for removal greatly reduces any risk (not grinding is even better). Asbestos Cut Gaskets is still used in most of the rest of the world and is a very effective low cost material.
It is usually desirable that the gaskets be made from a material that is compressible such that it tightly fills the space it is designed for, including any slight irregularities. The most common misconception when selecting a Cut Gasketss thickness is to choose a Cut Gaskets that is too thick. The thicker the material the more likely the material being contained can weep through the pores of the Cut Gaskets itself. This is a greater issue with some materials than others. A rule of thumb is to have the material thick enough to compensate for any surface face irregularities and to permit some compression. The required compression for your Cut Gaskets will depend many factors including:
2)Pressure being sealed
3)Size of bolts (assuming bolts are being used)
4)Number of bolts
5)Condition of the bolts
6)Lubrication on the bolts
All must be considered when determining torque. Torque data must be determined using all of the above and should be provided by an engineer. In most cases unless your gasket is a standard ANSI or API flange using Ring or Full Face gaskets torque data will be difficult to come by (due to staffing and the fear of law suits). In most cases the old tighten it tight enough to stop any leaks but not too tight as to completely crush the gasket is generally accepted.
Over compression of Cut Gaskets is a common problem with metal gaskets which have mechanically designed recovery built into the gasket. Over compression removes the Cut Gaskets ability to recover. This is also true of expanded PTFE, once over compressed it will have no recovery and therefore will not longer adapt to maintain a seal. The common strategy of "The more compressive load exerted on the gasket, the longer it will last" is generally true of elastomeric materials since elastomers (rubbers) are not compressible but deflect compression. Many materials such as non-asbestos compressed Cut Gasketss and beater addition (ie; Armstrong) materials contain elastomers in the mix of material they are produced from, making them difficult to over compress.
One of the more desirable properties of an effective Cut Gaskets in industrial applications is the ability to withstand high compressive loads. Most industrial gasket applications involve bolts exerting compression well into the 14 MPa (2000 psi) range or higher. This is why Non-asbestos Cut Gaskets are so widely used in industrial Cut Gaskets applications.
American Seal & Packing Cuts Gaskets of all types, Including: PTFE, compressed non-asbestos, vegetable fiber, beater add, cork, and various rubbers - Nitrile, Buna-N, SBR, EPDM, Viton®, FKM, Hypalon, Aflas®, natural rubber, closed cell, open cell, Neoprene, GRAFOIL® Flexible Graphite and other "soft goods".
Gaskets can be cut based on your drawing or sample of the gasket you desire. Basic I.D x O.D shapes can be cut by hand however most gaskets require a die.
Gasket materials are available in rolls or on pallets depending on type and quantity. Name brands we can provide include; Brand G®, Donex, DX Seal, Mainland Sealing, Klinger, Johns Manville, RM, Detroit, Utex and GRAFOIL® Flexible Graphite among other gasket styles.
So, if you want a cut gasket or gasket material so you can cut your own, we can help.
