Greater precision and accuracy. The process is suitable for producing identical parts in high volumes from batch to batch. 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 For over nine decades, New Process Fibre has provided customers with high-quality and innovative non-metallic solutions, including Teflon washers. Our Teflon washers find application in a wide range of industries—including automotive, HVAC, and plumbing—providing durable and reliable performance even when exposed to water, oil, chemicals, and high heat. Flat washers are used to distribute the load of a fastener, such as a bolt or screw, over a larger area. They can also be used to provide a smooth surface for the fastener to bear against, or to prevent damage to the material being fastened. Flat washers are usually placed between the fastener head and the material being fastened, and are often used in conjunction with nuts or other types of fasteners.

Manufacturers employ a few different methods to produce Teflon washers. Two of the most common manufacturing methods are compression molding and machining. As one of the largest gasket cutters in the United Kingdom, we make and supply PTFE gaskets in a broad range of different variants including, etched and filled grades. 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? When designing and assembling automobiles, manufacturers must balance competing needs. For example, they need to reduce car weight to minimize emissions and improve fuel efficiency but also incorporate non-critical parts to increase durability, longevity, and operator safety. Teflon washers enable them to fulfill both requirements; the lighter material allows them to satisfy all washer functions without adding significantly to the total weight of the car. Electrically isolating mounting screws. As Teflon doesn’t conduct electricity as easily as metal or plastics such as nylon, it is ideal for introducing electrical resistance.

PTFE Washers – Key Characteristics

Washers can be used across a wide variety of industries and applications but it is important you only use washers made from suitable material. The best washer material to use will depend on the application you require it for, and here at Stephens Gaskets we strive to accommodate as many different applications as we can. From stainless steel, rubber and plastic through to cork, brass and aluminium, we have a wide range of washer material to choose from. Our washer materials are all incredibly versatile in their uses and applications, and one of our most popular choices is our PTFE washers. We can provide the washers in a range of pre-cut sizes, but if you are looking for something more specific, our bespoke service can create custom PTFE washers UK made to your exact required measurements. PTFE washers: UK Made 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. 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. RH Nuttall Limited produce washers, gaskets, seals, strip and sheet PTFE for a variety of applications. General Characteristics PTFE washers are naturally highly chemical resistant and self-lubricating, which allows for accurate torquing and smoother operation.

Tightening nuts into place on bolts and other fasteners. Washers evenly distribute the pressure of a fastening point across a larger surface area to reduce strain and the risk of damage. 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. Faster turnaround. Compression stamping equipment can achieve up to 400 strokes/minute, enabling the production of hundreds of thousands of washers each day. 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.

PTFE Washers

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. Our PTFE washers come in a variety of shapes, from simple round or square designs to custom designs with several holes and or slots across the flange. We manufacture PTFE Gaskets from our complete range of Polytetrafluoroethlyene (PTFE) materials. Commonly referred to as Teflon (The well known brand name of The Chemours Company), PTFE has outstanding resistance to chemicals, a wide temperature range, withstanding (–200° C to +260° C) and excellent dielectric properties. 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. 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.
