HNBR70K O-Ring | O Ring Seal | High-Temp Oil-Resistant Seal
HNBR70K O-Ring | O Ring Seal | High-Temp Oil-Resistant Seal
Product Description
This HNBR70K O-Ring, sized 19x2.6mm, is a high-performance sealing component engineered for demanding oil-contact environments. Made from hydrogenated nitrile butadiene rubber, it delivers reliable sealing between -40°C and 150°C, with superior resistance to mineral oils, hydraulic fluids, and ozone. The black, one-piece circular design fits standard seal grooves in automotive engines, hydraulic valves, and industrial pumps, creating a durable barrier against fluid leakage. Its HNBR70K material offers exceptional anti-aging and compression set resistance, ensuring long-term performance even under dynamic operating conditions, making it ideal for critical sealing applications.
