1mm CS HNBR O-Rings

Product Overview

1mm CS HNBR O-Rings are precision sealing rings manufactured from hydrogenated nitrile rubber (HNBR), offering excellent resistance to high temperatures, oils, fuels, ozone, and aging. Designed with a fixed 1mm cross section (CS), these small-profile sealing rings provide reliable performance for compact and precision sealing applications.

Compared with standard NBR O-Rings, HNBR offers improved heat resistance, mechanical strength, and long-term durability, making it suitable for automotive, hydraulic, pneumatic, fuel system, refrigeration, and industrial applications.
