Tank Car Manway Gaskets
For Covers—Flat Profile
 |
Gaskets for covers fit into the groove of manway lids.
Flat-profile nozzle gaskets have metal mounting tabs that secure the gasket to the nozzle.
ePTFE— ePTFE gaskets are chemically inert, except to molten alkali metal and fluorine compounds. They have a corrugated stainless steel insert, so they compress without deforming at lower bolt loads than rubber. This means they create a tighter seal without causing bolts to loosen.
