Manway gaskets are used for a range of applications such as fuel tanks, boilers and other types of closed vessels. The gaskets involved are subject to many design requirements such as shape (round, oval, ob-round), closing mechanism (single stud bolt, several sealing bolts and hinged handles), pressure (standard fuel tanks to steam pressure vessels) and heat requirements. Any combination of the above design criteria means that the selection of a gasket material to suit is an important part of the overall production sequence.Â
