Polypac Hydraulic O-Rings for Hydraulic Systems
Polypac offers high-quality O-rings designed specifically for hydraulic systems. Our seals provide dependable performance in high pressure, frequent motion, and harsh working conditions. Built from proven materials and manufactured in our advanced facility, Polypac O-rings help prevent leaks, reduce downtime, and extend equipment life.
Reliable Materials
We produce O-rings in a wide range of materials to match different hydraulic fluids and temperatures. Common options include NBR (nitrile) for general hydraulic use, FKM (Viton) for high temperature and chemical resistance, EPDM for water-based fluids, silicone for extreme temperatures, and FFKM for the most demanding chemical environments.
