The PR-42N85 profile seal is manufactured from 85 durometer black Nitrile (NBR) and is designed to meet DIN 3869 specifications for axial static sealing in M42 X 2.0 hydraulic threaded fittings. Built to seal against flat faces in high-pressure hydraulic systems, this 1-1/4" profile ring ensures reliable performance, reduced leakage, and long-term resistance to deformation and twisting during installation.

The geometry of this seal minimizes mechanical stress and maintains sealing integrity in environments with pressure pulsation or vibration. Ideal for OEM and MRO applications across construction, agricultural, and fluid power systems, the PR-42N85 excels in static sealing where traditional O-Rings often fail.
