Types of  Gaskets

A gasket is a mechanical sealing component to fill the space between two parts. it can avoid leaking gas or liquid from the pipe, flange, container, etc. The Gaskets are always made of plastic, metal, rubber, wood, and ceramic. They are used in a wide range of applications, from industrial machinery to household appliances. In this article, you will learn the types of gaskets.

Types of Gaskets by Material

Metallic gasket

Rubber gasket

Rubber gaskets are made of Natural Rubber NR, Neoprene Rubber, Butyl Cyanide Rubber, Fluoroelastomer, Synthetic Rubber, Silicone Rubber Silicone Rubber, Fluoroelastomer, etc., mainly applied with some soft links.

Teflon sealing

virgin PTFE, filled ptfe， PFA plastic， FEP plastic， always used in strong acids and alkalis, high oil contamination, and extreme temperatures

Composite gasket

Composite gaskets are often made of a metal core, such as stainless steel, combined with layers of softer materials like graphite, PTFE (Teflon), or rubber. This construction provides the rigidity to withstand high pressures, while the softer materials ensure a tight, adaptable seal. It was used in the Automotive Industry, Oil and Gas, Chemical Processing, and Power Generation.

Types of Gaskets by Application

Industrial Seals:

Industrial gaskets must withstand extreme conditions, including high pressures, temperatures, and chemical exposure. Metallic and composite gaskets are frequently used in these applications.

Chemical & Oil Gaskets

Chemical & Oil gaskets are specifically designed to resist the corrosive nature of chemicals and oils. Teflon and rubber gaskets are common choices in this category, they offer excellent chemical resistance.

PEM & Alt Sealing

These kinds of gaskets are used in power electronics and alternative energy systems. They are designed to provide reliable seals in complex environments.

Flange Gaskets

Flange gaskets are in piping systems, that can be made from various materials depending on the pressure and temperature requirements. They are crucial in preventing leaks in pipelines.

Liquid Nitrogen Gaskets

These gaskets are designed for low temperatures, usually, we use a PCTFE Gasket sealing solution.

Types of Gaskets by Shape

Almost all of the gaskets need to be customized, so the gasket has many shapes, such as full face gasket, spiral wound gaskets, raised face flange gasket, gasket ring, Y gasket, V gasket, Corrugated gasket, square o rings. please check the image below.
