High Pressure Piston Seal Solutions by Polypac

Why Choose Polypac High Pressure Piston Seal

Polypac manufactures High Pressure Piston Seal products engineered for demanding hydraulic systems. Founded in 2008, we combine deep material science with precision manufacturing to provide piston seals that minimize leakage, reduce friction and extend service life under extreme pressure and temperature. As a scientific and technical hydraulic seal manufacturer, Polypac offers reliability you can specify into critical equipment.

Materials & Custom Options

We supply High Pressure Piston Seal components in advanced filled PTFE variants (bronze-filled, carbon-filled, graphite, MoS₂-filled, glass-filled) and elastomers including NBR, FKM, silicone, EPDM and FFKM. Custom compound development and molded rubber rings or O-rings allow seals to be tailored for specific pressure ranges, media compatibility and thermal demands — ideal for hydraulic cylinders, subsea actuators and high-pressure pumps.

Performance & Typical Applications

Designed for high-pressure piston duties, our seals deliver low friction, excellent extrusion resistance and consistent sealing under cyclic loads. Typical applications include construction and mining equipment, oil & gas actuators, injection molding machines and mobile hydraulics. Polypac High Pressure Piston Seal solutions protect systems against contamination, fluid loss and premature wear, improving uptime and reducing maintenance costs.

Quality, Testing & Innovation

Polypac’s custom rubber ring and O-ring factory spans over 10,000 m² with 8,000 m² of production space and advanced manufacturing and testing equipment. We maintain long-term partnerships with universities and research institutes to drive innovation in sealing materials and test methods. Every High Pressure Piston Seal undergoes strict dimensional, material and performance testing to meet demanding operational specifications.
