“These are Pex A expansion Pex and worked great for my new plumbing in my Airstream. I added these shut-offs for the sinks and toilet. No leaks. I used the DeWalt expansion tool.”
“Works great to allow a connection from 1/2" expandable pex to toilet or faucets. Very good quality, feels smooth and sure when turning off the water. I am not a plumber, but have completed a number of small to medium-sized projects with iron, copper, and Pex A and Pex B. I have found Pex A to be the easiest, most forgiving, and by far the fastest option.”
