Discover top-notch NBR O ring with resilience against oil, fuel, water, and petroleum fluids at Exactseal. Our extensive range of NBR O Rings, crafted from nitrile rubber (Buna-N), ensures exceptional resistance to various substances, making them ideal for hydraulic, pneumatic, automotive, and general industrial sealing applications.

Nitrile rubber’s robust mechanical properties and wear resistance make NBR O Rings reliable, although they aren’t suitable for high temperatures, ozone, or UV exposure. These O Rings come in diverse hardness levels, measured on the Shore A durometer scale (usually ranging from 70 to 90 Shore A). A higher durometer indicates increased hardness and compression resistance.

At Exactseal, we offer customizable NBR O Rings in various sizes, shapes, and colors, employing cutting-edge technology and equipment to ensure product precision and quality. Our commitment to safety standards is unwavering.

With a decade of experience in manufacturing and supplying NBR O Ring, our skilled team guarantees excellent service. Take advantage of our swift and efficient shipping of a vast NBR O Ring inventory, along with competitive prices and discounts for bulk orders.
