ABSTRACT:
This invention is for two probe hose connector fittings for tapping beer kegs that have a keg fitting with check valves for preventing flow of beer and gas until the probes are pushed down into position to open at least the beer valve. The probes are tubes, and in the prior art such tubes were cut diagonally across their lower end portions to form a valve engaging surface. This surface at the lower end of the tube was merely the end face of a part of the circumference of the tube and easily damaged because of its lack of inherent strength. The present invention makes the probes from bar stock and provides a construction that provides ample open area over part of its cross section for the flow of beer.
