High Pressure Polyurethane O-Rings, Gaskets & Parts
High pressure polyurethane O-rings, gaskets, seals, and custom molded parts are widely used in hydraulic, pneumatic, oil and gas, mining, automotive, and industrial machinery applications where exceptional abrasion resistance, extrusion resistance, and mechanical strength are required. Polyurethane elastomers, commonly referred to as PU or urethane materials, are engineered for sealing systems exposed to aggressive wear, pressure spikes, reciprocating motion, and harsh operating environments. These materials are frequently selected for hydraulic cylinder seals, backup rings, scraper seals, suspension components, rollers, bushings, valve components, and heavy-duty sealing systems requiring long service life under demanding conditions.
Canyon Components supplies high performance polyurethane sealing solutions including polyurethane O-rings, gaskets, seals, tubing, backup rings, custom molded rubber parts, and precision machined polyurethane components for high pressure industrial applications. Our team supports custom durometers, abrasion resistant formulations, oil resistant polyurethane materials, and Parker equivalent polyurethane compounds for hydraulic and dynamic sealing systems. We also assist customers with material selection, extrusion resistance optimization, and custom sealing geometries for challenging pressure environments.

Features of High Pressure Polyurethane O-Rings, Gaskets & Parts
- Polyurethane elastomers provide exceptional extrusion resistance in high pressure sealing systems where softer elastomers may fail or deform under pressure
- These materials offer excellent abrasion resistance and wear resistance for dynamic sealing applications involving reciprocating or rotary motion
- Polyurethane O-rings and seals maintain strong tensile strength and tear resistance under demanding hydraulic and pneumatic operating conditions
- High pressure polyurethane compounds are commonly used in hydraulic cylinders, valve systems, pumps, heavy machinery, and industrial automation equipment
- Polyurethane sealing materials provide excellent resistance to mineral oils, hydraulic fluids, greases, and many petroleum based lubricants
- These materials are frequently selected for dynamic sealing applications where long service life and low wear are critical
- Harder polyurethane compounds can significantly reduce extrusion damage in high pressure sealing glands with larger clearance gaps
- Polyurethane backup rings and anti-extrusion components are commonly used alongside O-rings and hydraulic seals to improve pressure capability
- Polyurethane materials provide excellent impact resistance and load bearing performance compared to many standard elastomers
- Custom molded polyurethane parts can be manufactured in a wide range of hardnesses, colors, and geometries depending on application requirements
- Canyon Components supplies custom polyurethane O-rings, gaskets, seals, tubing, and molded parts with strong availability and engineering support for industrial sealing systems
Limitations of High Pressure Polyurethane O-Rings, Gaskets & Parts
- Polyurethane materials generally have more limited high temperature resistance compared to FKM, FFKM, or Silicone materials
- Standard polyurethane compounds may hydrolyze or degrade in prolonged hot water or steam exposure depending on formulation
- Polyurethane sealing materials typically have reduced low temperature flexibility compared to Silicone or specialty low temperature elastomers
- Some polyurethane compounds may become harder at low temperatures, potentially increasing sealing friction in dynamic systems
- Polyurethane materials can exhibit higher friction compared to PTFE based sealing solutions in certain dry-running applications
- Extreme chemical processing applications may require Canrez® FFKM, PTFE, or specialty engineered materials instead of polyurethane
