Sealing Performance and Durability

Main Description

The O-ring 148x5 NBR 70 ShA is a precision-made industrial sealing ring designed for reliable operation in demanding technical environments. Manufactured from NBR (nitrile butadiene rubber) with a hardness of 70 ShA, this O-ring offers an optimal combination of elasticity, mechanical strength, and resistance to compression set. It is widely selected by engineers and maintenance teams for consistent sealing performance in industrial systems.

With an inner diameter of 148 mm and a cross-section of 5 mm, this O-ring is primarily intended for static sealing, while also being suitable for selected low-speed dynamic applications. The NBR compound provides excellent chemical resistance to mineral oils, greases, fuels, and commonly used hydraulic fluids. This makes the O-ring 148x5 a proven solution for hydraulic and pneumatic applications, as well as general industrial sealing tasks.

As a versatile rubber gasket, this O-ring is commonly used in pumps, valves, compressors, gearboxes, flanges, and industrial housings where a tight and durable seal is required. Its precisely controlled geometry ensures uniform contact pressure within the groove, reducing the risk of leakage and extending service life. The material’s abrasion resistance and elasticity contribute to high durability, even under cyclic pressure and temperature variations.

The O-ring 148x5 NBR 70 ShA is classified as a reliable technical sealing component for industrial production, maintenance, and overhaul operations. It integrates easily into standard groove designs and supports predictable performance across a wide range of operating conditions. Supplied as a pack of 100 pcs, it is ideal for B2B customers managing maintenance stock, series assembly, or long-term procurement planning.
