RS PRO Nitrile Rubber (NBR) O-Ring 0.75 in Inside Diameter 1 in Outside Diameter Shore 70 Hardness Italy 689-710

RS PRO 689-710 Nitrile Rubber (NBR) O-Ring provides reliable sealing in industrial and mechanical applications. This O-ring features a 0.75 inch inside diameter and 1 inch outside diameter with a thickness of 0.125 inch. The material composition is Nitrile Rubber (NBR), known for excellent resistance to petroleum products and abrasion, making it a go-to elastomer for sealing solutions.

Rated Shore 70 in hardness, this O-ring maintains performance under continuous operating temperatures ranging from -30°C to 120°C. It can withstand short-term exposure to temperatures up to 135°C. Its black color signifies standard industry quality suitable for a wide range of uses.

Designed for industrial sectors including automotive, plumbing, aerospace, and general engineering, this O-ring resists mineral hydraulic oils and greases. However, it should not be used with esters, ozone, retones, aldehydes, chlorinated, or nitro carbons.

These O-rings comply with BS4518 tolerance standards ensuring precision fit and reliable sealing. Their durability and versatility make them essential components for sealing joints and equipment that encounter petroleum-based fluids and need resistance to both high abrasion and temperature variations.
