Compatible with Silca Presta Chucks, you can use the hose barb to put this into any 3/16" hose and add thread onto a Schrader valve or connect a Presta chuck that has Schrader threads like SILCA. New Silca Thread on Schrader Chuck.
needed a new thread on schrader valve for my Coleman 150 12 volt compressor. Installed this with a 1/4 poly line and fitting on the head. Great quality, fit and finish.
In all my years playing with bicycles, I have yet to find a clip-on air chuck that actually works well. This marvelous thing solves it. (And if you worry about losing air while you unscrew it... I find that I lose only a small puff -- maybe a pound or two. Just be quick about it. No trouble at all.)
