Custom Die-Cut PTFE Gaskets

These custom die-cut polytetrafluroethylene (PTFE) gaskets are fabricated for a precise fit and are available in sizes from 0.25 in. to 60 in. dia. by 0.003 in. to 0.250 in. thick. They are chemically inert and unaffected by most corrosive liquids, vapors, and gases. The gaskets are made from virgin or filled PTFE, paraformaldehyde (PFA), thermally fused melamine (TFM), or expanded PTFE. The properties of these materials make the gaskets suitable for applications requiring durability and slipperiness. The gaskets can be filled with glass fiber, carbon, or graphite to achieve specific performance characteristics with respect to lubricity, wear, and heat resistance. Their operating temperature range is –400°F to 500°F, and they can be ordered to conform to U.S. Food and Drug Administration (FDA) and military specifications.
