ClearLoc PTC fittings from @legendvalve The translucent body makes it easy to see the pipe/tubing inside the fitting for a proper insertion depth. I know some are not fans of ptc fittings, that’s fine, no one is making you use them. Others see the value for certain installations, some use them often. The reality is almost every manufacturer offers them because there is a demand beyond the diy market, supply houses sell tons of them to pro contractors all the time 🤟🏼 | mechanical-hub.com
