TLDR: 🌟🌟🌟🌟🌟 Effortlessly installed a shut-off valve for my fridge's water supply, saving time and money without needing a plumber.I recently faced the challenge of moving my fridge, but the lack of a shut-off valve for the copper water tubing meant potentially turning off the house's water supply, which wasn't an option. To tackle this, I armed myself with a pipe cutter, a handy gadget, and a hopeful spirit.The installation process turned out to be surprisingly simple. The first end of the gadget connected with a reassuring "pop," signaling a secure fit. The other end was a bit more stubborn, not clicking into place right away. Sensing something amiss, I applied pressure to both ends simultaneously, and sure enough, the second "pop" confirmed a successful connection.When I turned the house's water back on and switched the new valve to the 'on' position, water flowed smoothly with no signs of leakage. The feeling of triumph was immense! This quick, five-minute fix cost just a fraction of what hiring a plumber would have, with the toughest part being just moving the fridge.This DIY solution proved to be a highly effective, quick, and cost-efficient way to add a necessary shut-off valve, enhancing the practicality of my kitchen setup.

My use was to replace one that had failed (knob was WAAAY stiff after 10+ years) on the feedline to my espresso machine. Works perfectly; these fittings are nice in that they're removable from the tubing without tools in seconds if you have some need to get it apart and the seal is made by O-ring and is very reliable.

Best RO unit I have seen in a long time. Easy instructions, packed good from factory and all parts are included. It's only been in for a week with only a small leak at spout.This company has a very good web site for ordering replacement filters when needed.Would recommend ISpring and will be ordering from them again.

I was changing the filters on my RO system when my valve started to leaked. I ordered this valve and it worked great and appears to be a good quality.

Works great. Wish it came with plastic end locks that I had to order separate.

Does exactly what it's supposed to do. No issues with 3/8" OD tubing. Just cut it square and push to fit. Zero dripping -- great seal.Seems solid but I'm not sure this is made for high-frequency use -- if you're turning it on and off 20 times a day for months on end, it's not hard to imagine performance eventually deteriorating...
