Watertight Locking Fill Caps

The Model FF Watertight Locking Fill Caps are heavy duty assemblies intended to prevent unauthorized fuel storage tank access when the fill or sounding lines of underground tanks extend above ground level or are under a manhole cover.

The assembly consists of a solid cast iron body with malleable iron hasp.  The brass cover is gasketed to provide a waterproof seal.  The body threads directly on to the line while the cap threads onto the body.  For easy cap removal, with the padlock off, the hasp swings out to become a rugged lever handle. Fill caps are available in 2" NPT size.
