This double stopcock with quick coupling by JBL gets connected with the hose lines of a filter or pump. It allows an easy and fast disconnecting of the device from the water circuit. The full water flow remains unchanged and there is no power reduction when used on the technical unit. The hose can be disconnected and connected safely, neatly and without water runback in one easy step. This makes a disassembly for cleaning or maintenance of technical systems much easier.

The double stopcock is available for three hose sizes: 13 mm, 17 mm and 20 mm. Consisting of extremely robust POM/ABS synthetic it is fresh and seawater restistant. However, it's not designed for tap water pressure (4 bar).
