Main description

The O-ring NBR 12x1,5 mm 70 ShA is a reliable nitrile rubber sealing ring designed for industrial and technical applications where high sealing efficiency and chemical resistance are required. Made of NBR, this O-ring provides excellent resistance to oils, lubricants, and many industrial chemicals. With a hardness of 70 ShA, it offers optimal elasticity and long-term dimensional stability, ensuring reliable sealing even under continuous operation, vibration, or pressure changes.

The 12x1,5 mm size meets standard industrial requirements, allowing for fast and accurate installation in typical grooves. A pack of 100 pieces is ideal for industrial maintenance, production departments, and workshops, reducing downtime and supporting efficient maintenance cycles.

NBR O-rings are suitable for both static seals (between stationary surfaces) and dynamic seals (on shafts, pistons, or other moving elements). Their versatility makes them perfect for hydraulic circuits, pneumatic systems, industrial machines, valves, and piping systems. High-quality NBR ensures chemical resistance, dimensional stability, and long-lasting elasticity, making it a trusted solution for industrial and technical sealing applications.
