The PR-33N85 profile seal is molded from 85 durometer black Nitrile (NBR) and engineered for use with M33 X 2.0 hydraulic fittings in accordance with DIN 3869 specifications. Designed to function as a static axial seal, this 1" profile ring delivers reliable sealing performance in high-pressure hydraulic and fluid systems. Its specialized design eliminates twisting during installation, resists extrusion, and maintains a low compression set for consistent, long-term sealing.

The PR-33N85 is commonly used in threaded hydraulic ports, valves, and manifolds where mineral oil-based fluids are present. It is an ideal upgrade from traditional O-Rings when dimensional stability, vibration resistance, and ease of installation are required.
