Comprehensive Guide to O-Rings and Rubber Seals
O-rings are essential components in various industries, providing reliable sealing solutions for a wide range of applications. They are circular rubber seals that prevent the leakage of fluids and gases, making them crucial in hydraulic and pneumatic systems. This guide will delve into the types, technical features, and applications of O-rings, highlighting key manufacturers such as Haisun Rubber, Jinwo Parts, QL Rubber, and Savvy Rubber.
Understanding O-Rings
O-rings are designed to fit into a groove and are compressed between two surfaces, creating a seal. Their circular cross-section allows them to maintain a tight seal under pressure, making them ideal for static and dynamic applications. The materials used in O-rings can vary, affecting their performance in different environments.
Technical Features of O-Rings
The effectiveness of O-rings is determined by several technical features, including material composition, hardness, temperature resistance, and chemical compatibility. Below is a comparison table summarizing these features:
