I use the Clippard air fill ones as well. They work awesome. Also, why you are there pick up some of there tee's and crosses. They are very good, solid built unit. They don't have nipples threaded in to the body, but the whole body is one unit. Also, there airline is very supple and tough. I use all there air supply stuff except for pressure gauges. I like there airline much more then the stuff typ. avaliable from jet retailers. It seals much better and have yet to have any leaks at any fittings on retracts, or fittings. IMHO.
