PU Polyurethane O-Rings & Seals

Polyurethane is the toughest, most extrusion-resistant, and most abrasion-resistant of all elastomeric sealing materials. Polyurethane O-rings can withstand pressures up to 5,000 psi with a 2.5 mm extrusion gap. Polyurethane is also very resistant to explosive decompression and has excellent properties over a wide temperature range.Polyurethane O-rings are used in a wide variety of products, including quick- disconnect hydraulic fittings, hydraulic cylinders and valves, pneumatic tools, CO2 firearms, or for applications requiring extreme abrasion or extrusion resistance.
