Urethane Piston Seal - Polypac Polyurethane Hydraulic Seals

Urethane Piston Seal by Polypac — Durable Polyurethane Solutions

Features & Benefits

Polypac's Urethane Piston Seal offers exceptional wear resistance, high tear strength, and superior rebound for long service life in demanding hydraulic systems. The Urethane Piston Seal minimizes extrusion and heat buildup while ensuring consistent dynamic sealing and low friction across a wide temperature range.

Materials & Performance

Made from engineered polyurethane formulations, our Urethane Piston Seal balances hardness and elasticity to resist abrasion, cutting, and hydrolysis. We optimize polymer blends for specific pressures, speeds, and media—ensuring reliable performance in oil, water-glycol, and specialty fluids.

Common Applications

Ideal for hydraulic cylinders in construction, mobile equipment, industrial presses, and material handling, the Urethane Piston Seal performs well in high-cycle, high-load environments. Its combination of resilience and dimensional stability makes it a go-to choice for heavy-duty piston sealing.

Customization & Sizes

Polypac provides custom grooves, lip geometries, and integrated backup rings for tailored sealing solutions. Our factory supports large-volume production and small-batch prototyping—producing metric and imperial sizes, custom cross-sections, and assembly-ready components.

Manufacturing Expertise

Founded in 2008, Polypac has evolved from PTFE-filled seals to a full portfolio that includes O-rings (NBR, FKM, silicone, EPDM, FFKM) and bespoke polyurethane components. Our 10,000+ m² facility and advanced production equipment ensure consistent quality and fast lead times for Urethane Piston Seal orders.

Quality Assurance & Testing

We perform dimensional inspection, hardness profiling, tear testing, and simulated service life trials. Collaboration with universities and research institutes reinforces our materials development and process controls to meet strict hydraulic standards.
