High Temperature Piston Seal — Reliable Sealing for Extreme Conditions

Polypac offers specialized high temperature piston seal solutions designed for hydraulic and pneumatic systems operating under elevated temperatures and harsh environments. Backed by over a decade of material science expertise and collaboration with leading universities, our seals balance thermal stability, wear resistance and low friction to maximize uptime and service life.

Why Choose Polypac High Temperature Piston Seal

As a scientific and technical hydraulic seal manufacturer, Polypac focuses on performance-driven design. Our high temperature piston seal products are developed with an emphasis on dimensional precision, consistent compression set resistance, and proven compatibility with hydraulic fluids. We provide reliable sealing that reduces leakage and maintenance cycles.

Advanced Materials & Performance

Polypac began with filled PTFE formulations and expanded to a broad material portfolio—bronze-filled PTFE, carbon-filled PTFE, MoS₂-filled PTFE, graphite and glass-filled variants—plus NBR, FKM, silicone, EPDM and FFKM O-rings. For high temperature piston seal applications, we select and test compounds to withstand thermal aging, extrusion and frictional heat while maintaining seal integrity.

Customization, Testing & Quality Assurance

Our custom rubber ring and O-ring factory spans over 10,000 m² with state-of-the-art production and testing equipment. Polypac offers tailored geometries, compound formulations and thermal endurance testing to meet specific operating ranges. Long-term partnerships with research institutions ensure our solutions follow the latest standards and innovations.

Typical Applications

High temperature piston seal products from Polypac are ideal for industrial hydraulics, injection molding, downhole tools, aerospace actuation and other systems exposed to elevated temperatures or aggressive media. We optimize each seal for friction control, leakage prevention and long service intervals.
