Procurement Intelligence
The RS PRO Standard Nitrile O-Ring is a general-purpose sealing component designed for hydraulic, pneumatic, and fluid transfer applications. Installation involves groove mounting in static or dynamic seal positions. Critical verification: confirm bore diameter (0.351in) matches the groove ID precisely, as undersizing causes extrusion and oversizing reduces sealing contact pressure.
Hydraulic pneumatic fluid sealing
Before ordering — verify:
☐ Bore diameter verification
☐ Fluid compatibility check
☐ Temperature range validation
