IWISS Ratcheting PEX Cinch Tool for 3/8-Inch to 1-Inch Stainless Steel Clamps with Calibration Gauge - Meets ASTM F2098 Standard - Perfect for Plumbing, HVAC, and Water Supply Line Installation

The frostfree sillcock for my front yard needed to be replaced after 20+ years of use. Washer was bad, and the rusty screwhead holding it broke. Minerals in our local water are hard on plumbing parts. Better to replace than repair.Noticed that new sillcocks aren't exactly the same length as the existing. The best quality sillcock I could find was 3/8" shorter than the one I was replacing. I remembered replacing the front yard sillcock once before. Remembered dry fitting copper fittings and various short lengths of 1/2 inch copper until the connection between the sillcock and the 1/2 inch copper supply pipe was just right. Then sweating the joints. Hmmm. Did not want to spend my Saturday morning repeatedly cutting small lengths of copper pipe until I got just the perfect little piece that worked.Read up on PEX and decide snipping off little lengths of PEX would be a lot faster. And would simplify any future sillcock replacement.Access to pipes through garage wall was easy. Desoldered the necessary copper joints and removed old fittings. Then sweated in a new 1/2 inch copper to 1/2 inch PEX adapter to supplying pipe. Then tightened a 1/2" female copper to 1/2" PEX adapter to end of new sillcock. Measured, cut and test fitted PEX pipe to fit. Need a few tries, but easy to snip with a PEX cutting tool, and PEX is cheap. Slid on a couple of 1/2 inch Sharkbite clamps, used this clamping tool to tighten, and voila, job done.Couldn't understand why the big box stores charge $40+ for tools to cinch PEX clamps. Glad I found this item only. It worked great. Fast, easy, no leaks.
