NBR O-Ring | O Ring Seal | Oil-Resistant Engine Seal
A75K NBR O-Ring | O Ring Seal | Oil-Resistant Seal for Equipment
Product Description
These GSK NBR O-Rings are high-quality sealing components crafted from tested nitrile butadiene rubber. Designed for reliable performance in oil-contact environments, they maintain excellent elasticity and sealing integrity between -40°C and 120°C. The black, one-piece circular construction fits standard seal grooves in engines, hydraulic systems, and industrial machinery, providing a tight, long-lasting barrier against oil and gas leakage. Their robust material ensures resistance to wear, aging, and compression set, making them a trusted choice for both static and dynamic sealing applications
