46PCS Air Hose Fitting Kit, NPT Thread Push To Connect Fittings, Nylon Tubing 1/4, 3/8, 1/8, 1/2" Quick Connect, Air Line Fittings assortment kit for Automotive Car or Industrial Workshops

This is a nice assortment of fittings. I've used some for some pneumatic fixturing on a CNC router. The set came with a nice tubing cutter that works great, that I wasn't expecting, because it's not shown in the first photo in the listing, but I went back and looked, and it is mentioned, and it is in other photos. The push to connect fittings work great, the tubing pushes in easy and the release rings work well. The only issue is there is pre-applied sealant to the threads on the threaded fittings, but this sealant doesn't work at all, even after tightening the threads as hard as I could, they still leaked, a few wraps of Teflon tape and they work perfectly fine. If the fittings did not have this sealant on them, I would never think to put them together without Teflon tape, so they would have been better off to just not bother with the sealant. The Teflon tape isn't a big deal, and so, while I thought it worth mentioning, I don't feel it's worth docking a star over.

A convenient little set with a variety of options
