PTFE gaskets are supplied in a variety of grades designed to meet a wide range of sealing requirements. They provide excellent chemical resistance, high dielectric strength, and perform reliably across extensive temperature ranges. Their low moisture uptake, resistance to corrosion and hydrolysis, along with a notably low coefficient of friction, make them well-suited for sealing applications involving rotary or linear movements.
Our selection includes virgin PTFE and expanded virgin PTFE, both meeting current FDA regulations, making them ideal for use in food, beverage, and pharmaceutical industries. Expanded Virgin PTFE offers superior compressibility compared to standard virgin PTFE, making it particularly effective for sealing fragile, worn, or uneven flanges. Additionally, we stock various other grades enhanced with fillers such as bronze, carbon, glass, 316L stainless steel, and metal-detectable options. Further details on each grade can be found through the links in the table below.
AMG Sealing specialises in precision CNC cutting of PTFE gaskets, seals, and washers, accommodating both single-piece and bulk orders. We produce dovetail, picture frame, and standard flange gaskets, and can manufacture to bespoke dimensions. For assistance with measuring flange and picture frame gaskets, please consult our step-by-step guide on 'How to Measure a Gasket'.
