PTFE Piston Seal Solutions from Polypac

Polypac's PTFE piston seal range is engineered for demanding hydraulic and pneumatic applications where low friction, excellent chemical resistance, and long service life are essential. Our PTFE piston seal portfolio includes filled and self-lubricating formulations—bronze, carbon, graphite, MoS2 and glass-filled PTFE—designed to reduce wear and extend maintenance intervals while ensuring tight dynamic sealing under high pressure.

High-performance Materials

Each PTFE piston seal is manufactured using High Quality-filled PTFE compounds tailored to operating conditions. Whether you need improved thermal stability, abrasive wear resistance or anti-galling performance, our material options provide consistent low friction and dimensional stability. PTFE piston seal materials resist aggressive fluids and maintain sealing integrity across wide temperature ranges.

Custom Manufacturing & Sizes

Polypac specializes in customized sealing solutions. Our 10,000+ sqm production site and advanced equipment enable efficient production of bespoke PTFE piston seal geometries, tight tolerances, and small to large volume runs. We work with clients to optimize cross-sections, backup rings, and mating surface compatibility to achieve reliable performance in special working conditions.

Precision Production & Testing
