These caps are threaded into the top of stationary (non-mobile) above ground fuel storage tanks, where they serve 2 purposes: a) they can be used as a thread in and lockable fuel filter cap. b) They protect the tank from expansion or implosion, the internal relief valve is normally closed, but opens to relieve internal pressure or vacuum.
