The Sanke Keg Coupler is designed to fill and wash kegs that use an American Sankey D System type valve. It features a full stainless steel body and probe, is resistant to chemicals, and won’t wear down or chip away like chrome-plated brass. Inlet and outlets are larger than standard couplers and use 1/2″ barb connections. Does not include a pressure relief valve (PRV) for sanitary purposes.
