Boiler Cover Gaskets

A boiler door gasket is an oval or round gasket placed between cover and shell on handhole and manhole covers of steam and high-temperature water boilers. As internal boiler pressure presses the cover, the gasket compresses and seals.
It is stocked in eight sizes from 9″ to 15″. It is a spare part that should be renewed each time the cover is opened for boiler inspection, internal cleaning and periodic maintenance.
Main Applications
- Steam boiler handholes
- Steam boiler manholes
- High-temperature water boilers
- Pressure tank inspection covers
- Periodic boiler maintenance

Which material? A boiler door gasket should be chosen from material suited to the boiler pressure and temperature and renewed every time the cover is opened; reusing an old gasket creates a leak risk at start-up.
