Buna-N O-Rings 90D

Buna-N (Nitrile) O-Rings 90 Duro for High Pressure Applications

Hard Buna-N O-Rings are better suited for higher pressures and abrasion than other Buna-N O-Rings. They are suitable for a broad range of fluids including oils, water, and mild chemicals. Tube fittings and adapters are supplied with 90 durometer hard nitrile (Buna-N). These O-rings are well suited for most industrial hydraulic and pneumatic systems. They have high extrusion resistance making them suitable for very high pressure static applications. Nitrile O-Rings are used as a face to face gasket style seal or as a shaft seal, and allow both rotary and linear movement. Use 90 durometer hard O-rings for applications with 1500 psi or higher pressures.

Operating temperature: -40° to +250F°
