The Schradero is a push-lock Schrader chuck that does away with levers and threading. Push it on, it locks; slide the quick-release sleeve and it comes off. The body is high-grade aluminium and the synthetic elastomer face seals lose little to no air and see almost no wear, so it is built to last a lifetime. It makes an ideal companion for a workshop compressor as well as a track pump.
Choose the thread-on version to fit a threaded pump head, or the hose-barb version to fit straight onto a hose.
