Polypac Hydraulic O-rings for seals

Polypac Hydraulic O-rings for seals

Overview

Hydraulic O-rings for seals are essential components that ensure leak-free performance across hydraulic cylinders, valves, pumps and rotary unions. Polypac combines scientific research and hands-on manufacturing experience to produce O-rings that meet the highest industry requirements. Since 2008 we have developed materials and designs that address pressure, temperature, and chemical exposure commonly encountered in hydraulic systems.

Materials & Performance

Polypac supplies O-rings in NBR, FKM, silicone, EPDM and FFKM, plus specialized PTFE-based compounds developed from our earlier filled PTFE work (bronze, carbon, graphite, MoS₂ and glass fills). Each material is selected for specific attributes—oil compatibility, compression set resistance, temperature range, and chemical stability—so your hydraulic O-rings for seals perform reliably under static and dynamic conditions.

Customization & Manufacturing Capability

Our custom rubber ring and O-ring factory spans over 10,000 m² with 8,000 m² of production space and advanced molding and testing equipment. Polypac offers tailored dimensions, compound formulations, and post-processing (e.g., heat aging, anti-extrusion features). We collaborate with universities and research institutes to refine compound recipes and manufacturing tolerances for specialized working conditions.

Applications & Industries

Hydraulic O-rings for seals from Polypac are widely used in construction machinery, agricultural hydraulics, mobile equipment, industrial presses, aerospace actuators, and oil & gas tools. Our products are engineered for high-pressure sealing, resistance to hydraulic fluids and additives, and long service life even in abrasive or chemically aggressive environments.

Quality Assurance & Testing

Quality is validated with comprehensive mechanical and chemical testing: hardness, tensile, elongation, compression set, aging, and compatibility tests. Advanced in-house inspection and strict QA protocols, combined with academic partnerships, ensure consistent batch-to-batch performance and traceability for critical hydraulic O-rings for seals.
