Dixon 2000L automatic pressure/vacuum relief cap for stationary fuel tanks. Zinc construction provides corrosion resistance. Automatically relieves pressure and vacuum to ensure safe tank operation.

Applications

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.

Construction

Die cast zinc body, brass screen

Features

Pad-lockable to prevent fuel theft and tampering

Safety Notes
