Nitrile-Butadiene O-Ring, commonly known as NBR O Ring, is a temperature-resistant O-ring designed to
resist high pressure and high temperatures. It is made of a special type of nitrile-butadiene rubber that is
able to withstand a wide range of temperatures and pressures. It is mainly used in engineering, automotive,
oil and gas, and other industrial applications. The NBR O Ring has a compression set of less than 25%,
with a tear strength of 25N/mm, and a volume resistivity of greater than 1×1014Ω·cm. It is available in black
and is certified with UL94-V2 flammability rating. It is ideal for high-pressure sealing applications, such as
hydraulic and pneumatic systems.
