The Kegco KTS97D-W Commercial Grade D System Keg Coupler is compatible with all domestic brand sankey kegs. It has a stainless steel body and probe for maximum durability and cleanliness. This keg tap has a clickable lever handle that easily clicks up and down to engage the keg, making it more convenient than the conventional lever style keg couplers that need to be pulled out before being pushed down. It also features a 55-psi pressure release valve to prevent over pressurizing the keg.
