Teflon is hydrophobic, meaning it resists mixing with water. Compared to nylon, it has a higher melting and better chemical resistance. These qualities make it suitable for equipment systems regularly exposed to moisture or requiring significant amounts of lubrication. PTFE washers and PTFE gaskets can be supplied not only in its virgin state, but also with carbon and/or glass inserted into it leaving the finished product more durable and able to withstand even higher temperatures. Ask a member of our sales team for more information. Data sheets can be supplied free of charge upon request. For a number of years, metal served as the default material for washers. However, the introduction of durable and reliable plastics, such as Teflon, has led to the acceptance of plastics as a suitable alternative.
Furthermore, it can handle up to 500 volts per mil and temperatures up to 600 degrees F while maintaining dimensional stability, resistance against creep, and the anti-frictional properties for which the product is so well known. This means that with these products, one can expect consistent, long lasting performance.
Why Choose Superior Washer & Gasket Corp.?
PTFE washers are naturally highly chemical resistant and self-lubricating, which allows for accurate torquing and smoother operation. At New Process Fibre, we maintain over 10,000 dies ranging from .080–10 inches in our in-house manufacturing facility. Combined with our custom tooling capabilities, this quality allows us to produce Teflon washers in virtually any size to meet a customer’s needs. Greater precision and accuracy. The process is suitable for producing identical parts in high volumes from batch to batch. Teflon washers find application in virtually every industry, including in the following: Automotive
After all, a washer is a piece of precision engineering. Therefore, having the right measurements can be the difference between a perfect seal and a leaky joint. Can you cut PTFE Washers to length? Our flat washers are manufactured to exceptionally high standards and compliant with DIN 125 specification. These can also be used in combination with an array of different material fasteners depending on your application. Available in sizes M3- M12. PTFE washers are strong, durable, and have one of the lowest coefficient friction levels of any other solid material. They are also chemically resistant and non-conductive with excellent dielectric properties. Plus, PTFE is an excellent insulator and is FDA-approved. Its rust resistance allows washers made from it to withstand moisture from car fluids and the environment.Advanced Seals and Gaskets Ltd uses years of experience and globally sourced materials to produce our vast catalogue of Seals and Gaskets along with associated foam and rubber products. Our Cellular Sponge Rubber range is vast and varied with differences in density, grade, quality etc which can all be tailored towards a particular application. Manufacturers employ a few different methods to produce Teflon washers. Two of the most common manufacturing methods are compression molding and machining. It also has the lowest coefficient of friction of any solid material, even at high speeds, which means that it often does not require lubrication. In cases where higher levels of lubrication are desired, you only need to lubricate Teflon™ PTFE products once — products made from the material are virtually maintenance-free. Applications Compared to metal, nylon and Teflon offer greater application versatility and durability when used in the manufacture of washers. While both are synthetic polymer materials with excellent mechanical strength and frictional resistance, they vary in regard to best use cases due to the differences in their manufacture and, consequently, their physical and chemical characteristics. For example: Its chemical resistance enables washers made from it to remain stable even when exposed to compounds such as road salts and pollution.
One of our main product offerings is non-metallic washers—i.e., plastic or fiber disk-shaped hardware components featuring a center hole. When used alongside a compatible fastener—such as a nut or bolt—washers serve several functions including: 1) ensuring the even distribution of pressure across the fastened surface, 2) acting as a spacer or isolator, and 3) mitigating the risk of the assembly loosening due to vibration and other environmental factors. Thermal insulating washers are made out of a material called PTFE. PTFE is a polytetrafluoroethylene (PTFE)-based synthetic fluoropolymer of tetrafluoroethylene, a high-molecular-weight compound consisting of carbon and fluorine — and is one of the most commonly used artificial substances in the world. As our longtime customers know, there are so many reasons to choose Superior Washer & Gasket Corp. as your source for any washer and shim you could need.

Our Capabilities And Services Teflon™ is an outstanding thermal insulator and the most chemically resistant plastic available today. In fact, it is one of the only known materials that is completely impervious to damage from almost all corrosive fluids.
Custom PTFE Washers
PTFE can be divided into two main styles. Virgin PTFE, which is fairly hard, like plastic, however it will still compress to make a seal between two faces. Expanded PTFE is more like a sponge, making it ideal for sealing damaged, glass or plastic flanges because it compresses more easily than the Virgin grade. Excellent dielectric properties– one of the best thermally established and non-conducting plastic materials making it suitable for electrical insulators in circuit boards.
Being chemically inert, except for some alkaline metals, means PTFE Gaskets are the seals of choice in food, pharmaceutical and chemical sectors. Compared to other nonmetallic materials, it is relatively expensive — this is partly because it has some of the most beneficial properties of any nonmetallic material and is as such in high demand. Thermal insulating washers are found in nearly every industry, including aerospace, automotive, heating and cooling, plumbing, appliances, the list goes on. And thanks to its many unique characteristics, it’s also a popular choice for washers and spacers. Its texture allows other components and parts to glide over them easily and being thermal but remaining non-conductive, also makes them a popular choice for use in circuit boards. Industry professionals in the plumbing industry generally turn to non-metallic washers for their operations due to the near-constant exposure of equipment and systems to water and other fluids. Non-metallic washers offer greater resistance to water-related issues such as corrosion. Additionally, Teflon’s near-complete resistance to water and oil and temperatures up to 600° F allow it to retain its form and integrity even when exposed to excessive moisture and high heat.
Absolutely! As a leading PTFE washer UK supplier we have state of the art, automated machinery allowing us to produce custom PTFE washers for our customers. Can you cut PTFE Washers to squares? A washer is a small circular component that is specifically designed to improve the seal, alignment or space between two other parts inside a device. When there are gaps or loose fitting components inside machinery, there is a risk of movement that can then lead to friction damage. If movement continues to occur between poorly fitted parts, the inside of the machinery could suffer from long-term damage that could jeopardise its safety and performance. By fitting a washer in place of any gaps, you create a tighter fitting alignment, therefore preventing unnecessary movement.
