Frequently asked questions
What is a gasket?
A gasket is made from a compressible material that is used to create a seal between two stationary faces such as pipe flanges.
Why will I need a gasket?
You need a gasket to create a seal, as it is extremely difficult to achieve completely smooth faces on metalwork. Also, potential erosion and corrosion of the faces over time could cause the joint to fail without a gasket.
How does the gasket work?
To be effective a gasket must be subject to sufficient force when being seated for it to compress and make the seal. Sufficient pressure must be applied and maintained once seated, to retain the seal.
Do I need to know anything else?
Yes, it is important that the chosen material for the gasket is suitable for the media it is coming into contact with, and that it can handle the temperature and pressure.
