Easy to install on travel trailer bathroom sink. Now, I have an easy way to cut water supply to the sink. It is so easy to install and has no leaks. It worked perfectly with the faucet I got here at Amazon

These work fine. I installed several of these for undersink shutoffs on 1/2" copper pipe. Many people don't like these "push on" valves, but I have done a lot of research and they have a great track record. It is VERY important to make sure the pipe is deburred and ROUND. I also use a small amount of silicone grease on the pipe and gently work the fitting onto the pipe. For copper pipe, you can remove the stiffener in the inlet side which will help with water flow. The stiffener is there for PEX or other flexible pipe and is not needed for the rigid copper. These are a little rough cast on the exterior, but the valve, o-ring and retention rings seem to be of good quality. No leaks!

Provides better flow than a piercing valve

Fit perfect our sink in the kitchen.

I needed to install a laundry room sink with 1/2" copper stubs in a new-build house. After cutting and cleaning the pipes, these installed easily (I did push pretty hard given what I had read about potential problems) and have been working perfectly for a month.

Delivered to door so saves $ on gas and the trouble finding it.

It was actually really easy, cut the pipe and it just popped right on and haven't seen any leaks in the last 6 or so months
