PTFE gaskets from R4 Gaskets are engineered to meet a wide range of sealing needs, offering unparalleled resistance to chemicals, high dielectric strength, and a broad operating temperature range. Their excellent resistance to moisture absorption, corrosion, and hydrolysis, combined with an extremely low coefficient of friction, makes them ideal for rotary and linear movement applications. Available in thicknesses ranging from 0.5mm to 25mm, our PTFE gaskets cater to various industrial requirements.
Grades of PTFE Gaskets
Our most popular grades include virgin PTFE and expanded virgin PTFE, both of which comply with current FDA regulations, making them suitable for the food, beverage, and pharmaceutical industries. Expanded virgin PTFE is especially useful for delicate, worn, or damaged flanges due to its increased compressibility. We also offer PTFE gaskets with additional fillers, such as bronze, carbon, glass, 316L stainless steel, and metal-detectable variants.
Precision Manufacturing
At R4 Gaskets, we utilise advanced CNC machinery to cut PTFE gaskets, seals, and washers with precise tolerances. Whether you need a single gasket or a large volume order, we can manufacture dovetail, picture frame, or standard flange gaskets according to your specifications. We also work with bespoke dimensional drawings. For guidance on measuring flange and picture frame gaskets, please refer to our step-by-step guide on ‘How to Measure a Gasket.’
