A Comprehensive Guide to Gaskets and Seals in China

Gaskets and seals are essential components in various industries, serving as mechanical seals that fill the gaps between two or more mating surfaces. Their primary purpose is to prevent liquid or gas leakage under various operating conditions. In China, the gasket and seal manufacturing industry has grown significantly, with numerous manufacturers offering a wide range of products tailored to meet specific application requirements. This guide will explore the different types of gaskets, their technical features, and the leading manufacturers in China.

Understanding Gaskets and Seals

Gaskets are typically made from various materials, including rubber, metal, and composite materials. The choice of material depends on the specific application, including factors such as temperature, pressure, and fluid compatibility. Seals, on the other hand, are designed to prevent the escape of fluids or gases and are often used in conjunction with gaskets.
