Polypac Low Friction Wear Ring — Reliable PTFE Hydraulic Seal

Overview

The Polypac Low Friction Wear Ring is designed to protect hydraulic cylinders, reduce metal-to-metal contact, and extend seal life. Built from advanced PTFE and filled compounds, this wear ring minimizes friction while resisting wear in demanding environments. Polypac combines decades of seal expertise with modern manufacturing to deliver consistent, dependable components.

Features & Benefits

Low Friction and Long Life

Our wear rings use specially formulated PTFE blends that lower operating friction and reduce heat build-up. That means smoother motion, lower energy use, and longer service intervals for your equipment.

Excellent Wear and Chemical Resistance

Filled PTFE materials such as carbon, bronze, or graphite provide improved wear resistance and tolerate common hydraulic fluids, ensuring stable performance across many working conditions.

Protects Seals and Cylinders

By preventing direct contact between piston and housing, the wear ring protects primary seals from extrusion and damage, improving overall system reliability.

Materials & Compatibility

Polypac offers wear rings in a range of PTFE compounds and compatible elastomer pairings. Typical combinations include bronze-filled PTFE, carbon-filled PTFE, and glass-filled PTFE, matched with NBR, FKM, EPDM, or other O-ring materials as needed for your hydraulic fluid and temperature range.

Applications

Ideal for hydraulic cylinders, piston assemblies, pneumatic systems, and heavy machinery. Suitable for mobile equipment, industrial presses, construction machinery, and any application requiring reduced friction and improved seal protection.
