Interstate Specialty Products” seats, seals, gaskets, washers, and related parts are fabricated to customer specification from PTFE, PFA, and TFM. PTFE components are engineered from various formulations of PTFE, PFA, and TFM to achieve specific performance characteristics with respect to lubricity, wear-, heat-, and chemical-resistance. Machined, die-cut, or stamped to match OEM design requirements, typical components include bearings, bushings, gaskets, seats, seals, spacers, and washers. Chemically inert and unaffected by most corrosive fluids, the PTFE components are suitable for operation from -400 F to 500 F and can be filled with glass fiber, carbon, or graphite. Capable of conforming to rough sealing surfaces, PTFE components are ideal for use in compressors, instruments, pipelines, pumps, and valves requiring slipperiness and durability.
