Comprehensive Guide to O-Rings: Types, Features, and Applications
O-rings are circular mechanical gaskets used to create a leak-free seal between two components. The o-ring sits in a groove and gets compressed during assembly between two or more parts, forming a reliable seal at the interface. O-rings are commonly used in mechanical designs as they are easy to make, inexpensive, and have simple mounting requirements. This guide will delve into the technical features, types, and applications of O-rings, highlighting key manufacturers such as Savvy Rubber, Hongjie Sealing, Zhonggao Seals, Chaoyue Rubber, and Hongju Silicone.
