RS PRO NBR Bonded Seal Washer 22.7 mm ID 30 mm OD 2 mm Thickness -70 Shore Bonded Seal 689-568

RS PRO 689-568 Nitrile Rubber (NBR) Bonded Seal Washer is a specialized component designed to ensure secure sealing in demanding industrial, automotive, and engineering applications. It features a robust construction with a bonded seal design, combining metal and elastomer for enhanced reliability and leak prevention. The washer is manufactured from premium NBR material, offering excellent resistance to petroleum products, greases, and mineral hydraulic oils.

This bonded washer is engineered with a precise inside diameter of 22.7 mm and an outside diameter of 30 mm, making it ideal for a range of fittings and pipe systems. The thickness of 2 mm contributes to its effective sealing capability, while a hardness of Shore 70 provides strength and resilience under repeated mechanical and pressure loads. The seal operates efficiently in temperatures from -10°C to 80°C, maintaining integrity in both low and moderate thermal conditions commonly encountered in industrial environments.

The RS PRO 689-568 washer meets CE, UR, and cUR quality standards, assuring compliance for use in regulated sectors. Its NBR material is widely regarded for high abrasion resistance, making it suitable for continuous operation and environments where exposure to oils, greases, or fluctuating temperatures is a factor. Applications include hydraulic couplings, fluid power systems, automotive assemblies, aerospace connections, and general fabrication where reliable prevention of leaks is critical.

This washer forms an important part of industrial maintenance and assembly, particularly where precise fit and long-term durability are required. Nitrile (NBR) bonded seals are selected specifically for environments requiring chemical resistance and a strong mechanical seal, making this product suitable for a variety of engineering and manufacturing processes.
