Hose End Cuff (with Quick Disconnect) - threads onto the tool end of your 1 1/2" (36mm) hose. For swivel use and quick disconnect of curved hand tube. Alto uses a "squeeze type" Swivel End Cuff (with disconnect) on some of its models. The newer part (#302001345) requires more hand strength to release the end tube. I prefer the style featured here with the thumb-release. 1 left in stock.
