Product
Description

Rubber O-rings (O-rings) are annular seals with a circular cross section, widely used in various mechanical equipment and hydraulic systems. Their main function is to prevent liquid or gas leakage, and they can provide efficient sealing performance in both static and dynamic sealing environments. Due to their excellent elasticity, they can adapt to different sealing surfaces and slight surface defects, and are one of the most commonly used sealing components in the industrial field.
