This cleaning cup is designed to be used with the keg coupler in the untapped position (lever handle up). Compatible with most US Sankey & Euro-sankey single valve couplers. It will not function as a series cup, if capped, since it has no ball lifter stem. Connect to line with standard faucet thread fittings. (1 1/8 x 18 unef).
If you have one of our cleaning kits, this adapter threads directly on to the hose end faucet adapter.
