Claim 1

In combination with a drum which includes a cylindrical sidewall and end walls closing off the ends of the drum, one of said end walls including a bunghole assembly providing access to the interior of the drum which includes an internally threaded, non-tapered, annular fitting and an annular collar concentric with the fitting, said collar overlying outer portions of the fitting and being secured to said end wall and securing the fitting in place, a faucet assembly including a tapered externally threaded stem with threads of largest diameter located inwardly from the free end of the stem, mounted with its threaded stem screwed into the internal threads of the fitting, a gasket surrounding said stem and bearing against said collar, and a hand-manipulatable nut having non-tapered internal threads of a diameter sufficient to receive the external threads of largest diameter in the stem, said nut being mounted on said stem and compressing said gasket against said collar with the gasket being effective to inhibit leakage past the threads of said stem and leakage between the fitting and collar, said stem being tapered from the free end of the stem inwardly on the stem beyond the region where the nut is located, the threads of the nut in reaction to the compression of the gasket jamming against the threads of the stem to inhibit leakage, the faucet assembly being mountable on the fitting through turning of the faucet assembly to advance the stem into the fitting and turning being stopped on the faucet assembly having desired orientation relative to the drum.
