NBR70 O-Ring | O Ring Seal | Oil-Resistant Industrial Seal
NBR70 O-Ring | O Ring Seal | Oil-Resistant Industrial Seal
Product Description
This NBR70 O-Ring, with a size of 8.10x1.60mm, is a high-performance sealing component made of premium nitrile butadiene rubber. Formulated to 70 Shore A hardness, it balances elasticity and structural stability, delivering reliable sealing performance between -40°C and 120°C. The black, one-piece circular design fits standard seal grooves in industrial machinery, automotive engines, and hydraulic systems, effectively preventing oil, gas, and fluid leakage. Its robust NBR70 material offers excellent resistance to wear, aging, and compression set, making it suitable for both static and dynamic sealing applications.
