Flair-It Sales 16880 Plastic Straight Stop Valve, 0.5' Size

Smooth quarter turn action. Easy to install.

I'm going through my whole RV and putting one of these at every faucet and the toilet water lines so when there is a leak detected you only have to shut off that particular water outlet and still have water to the rest of the RV.Makes doing repairs really nice when there is a problem and you can just work on that water line while you have water to the rest of the RV areas.Did a simple photoshop mock-up of how it works, very simple to use!

These worked great on my motorhome

Easy to use and works great

I ordered more than I needed because they are hard to find locally now. I keep them on the ready for problems. Also adaptable for other tubing projects.

It fit just right

Have bought dozens of items through Amazon. Have never taken time to write a review before, but no one else should have the problems I had. First, you'd better be pretty strong in order to get the pex onto these valves. Far more importantly, bought 7 and 4 of the seven leaked when the water was turn on - leaked a lot! Sharkbite or Elkhart products are easy to use and work! I only bought these because I could not fine a better product at the time and I wasted hours and money as a result.

Same as original , used cap screw to repair original , so didn't have to remove valve
