Gaskets are part of every boiler and steam or hot water system. They’re used around the many handholes and manholes provided for access and inspection, to prevent leaks in exhaust ducting, and wherever pipes are joined. If a boiler gasket fails the consequences are usually serious.
What is the purpose of a gasket?
A gasket stores energy, like a spring, and seals two mating surfaces that fail to perfectly meet. Wikipedia: “Fills the space between two objects, generally to prevent leakage between the two objects while under compression.
What type of gasket does steam use?
One good steam gasket material choice is Ethylene Propylene Rubber (EPDM.) EPDM gaskets will handle steam at temperatures up to 395°F (200°C) and also provide good resistance to dilute acids and alkalies, alcohol, ketones and automotive brake fluids. Styrene-butadiene rubber (SBR) gaskets are another good choice.

What is the difference between a flange and a gasket?
The terms “gaskets” and “seals” are often used interchangeably. The fundamental difference is that a gasket is a physical piece that goes between two flanges to create a seal at a joining point between two components. A gasket is a seal.
Do graphite gaskets need sealant?
Graphite seals and gaskets retain their properties at temperatures as high as 450oC, and have some other very useful sealing characteristics. … This slipperiness or low coefficient of friction is useful in gasketing or sealing. As mating surfaces are brought together graphite allows some slip.
