1.6mm CS HNBR O-Rings

Product Overview

1.6mm CS HNBR O-Rings are precision sealing rings manufactured from HNBR, designed for applications requiring a slightly larger sealing profile than ultra-thin O-Ring sizes. The 1.6mm cross section provides a balance between compact installation and reliable sealing performance.

Compared with standard NBR O-Rings, HNBR provides improved heat resistance, mechanical strength, and long-term durability. These sealing rings are widely used in automotive systems, hydraulic and pneumatic equipment, fuel systems, refrigeration equipment, and industrial machinery.
