From classic rubber O-rings to advanced filled PTFE rings, our product line balances tight tolerances, long service life, and compatibility with oils, fuels, and aggressive media. Each o ring seals variant is manufactured to meet industry standards and tailored to your dimensional and material needs.

Materials & Performance

We offer o ring seals in NBR, FKM, silicone, EPDM, and FFKM as well as bronze-, carbon-, graphite-, MoS₂- and glass-filled PTFE. Material selection is driven by temperature range, chemical resistance, wear characteristics, and dynamic or static sealing conditions. Polypac’s material development focuses on low friction, extrusion resistance, and durability for high-pressure hydraulic systems.

Custom Manufacturing & Quality

With a custom rubber ring and O-ring factory spanning over 10,000 m² and 8,000 m² of production space, Polypac combines advanced equipment with rigorous testing protocols. Our QA includes dimensional inspection, hardness testing, and performance verification under simulated working environments. This infrastructure ensures every batch of o ring seals meets client specifications and regulatory requirements.

Typical Applications

Polypac o ring seals are widely used in hydraulic cylinders, valves, pumps, compressors, automotive systems, and lubrication equipment. We specialize in bespoke sealing solutions for extreme temperatures, high pressures, corrosive environments, and reciprocating or rotary motions, ensuring system reliability and reduced maintenance costs.
