Product: O-ring

O-rings are a large product group used in a wide range of applications. These applications include high temperatures, oil and fuel contact, chemicals and hot water. We offer O-rings that are manufactured to meet your expectations in most segments of the industry. The O-rings are round sealing rings that are defined by 2 dimensions, inside diameter d1 and ring thickness (cross section) d2.

Material: NBR

NBR has excellent oil resistance thanks to the polar nitrile functionalities along the polymer chain. NBR is usually preferred for applications involving exposure to oil, fat, grease, and fuel due to its excellent resistance to non-polar fluid as well as to wear. The service temperature range of NBR is typically between -30 to 90ºC.
