I read an old post about these and thought i would try them as a psuedo quick disconnect. The're available at whitworths/bias. So screwed it tight onto the ss nipple (connected to ball valve), but the inside (white) plastic nipple still moves around and leaks between the black and white parts. Im presuming the white plastic too small for the inside diameter of the ss nipple . Are these a dead loss for my 1/2inch ss stuff, or am i doing something wrong ? Do they only work with an equivalent plastic nipple ?
