O-Ring 19.3x2.4 mm NBR 90 ShA GRN - Heavy Duty Oil Resistant Rubber Sealing Ring | Pack of 100 Pieces

High Hardness NBR O-Ring for Demanding Industrial Applications

The O-Ring 19.3x2.4 mm NBR 90 ShA GRN is a precision-manufactured sealing ring designed for demanding sealing applications requiring increased resistance to pressure, extrusion and mechanical loads. Manufactured from premium NBR (Nitrile Butadiene Rubber) with a hardness of 90 ShA, it provides excellent resistance to oils, greases, hydraulic fluids and industrial lubricants.

Compared to standard 70 ShA O-rings, the 90 ShA version offers improved resistance to deformation and is particularly suitable for high-pressure hydraulic systems and heavy-duty industrial equipment.

AI Overview
