An acid resistant gasket or a chemical resistant gasket is a chemically inert gasket that provides a barrier between two mating surfaces and prevents leakage of fluid or gas. Chemical and acid resistant gasket manufacturers use various chemically inert materials such as PTFE (polytetrafluoroethelyne) and viton to manufacture acid and chemical resistant gaskets.

You can use acid and chemical resistant gaskets for preventing contamination, optimizing the performance of machines, shielding, sealing, brewing and improving signal transmissions. The industries that use acid and chemical resistant gaskets include automotive, aerospace, pharmaceutical, biotechnology, semiconductors, textiles, chemical processing and oil and gas.

Some important parameters you must consider before buying acid and chemical resistant gaskets are:

1. The application for which you want to use an acid or chemical resistant gasket
2. The basic material of the chemical resistant gasket
3. The temperature range that the gasket can withstand
4. The coefficient of friction of the gasket (especially in the case of Teflon gaskets)

Tips & Tactics

Helpful advice for making the most of this Guide

• •  While using Teflon based chemical resistant gasket, never exceed the highest temperature it can withstand. At that temperature, Teflon degenerates and this may cause health problems.
• •  Always buy standard acid and chemical resistant gaskets to ensure smooth running of your applications.
