Review on 💧 JOHN GUEST USA 738260 John Guest 1/4-inch Push-Fit Shut-Off Valve Connector, Miscellaneous by Anthony Record

I keep replacing the ones I bought from big stores that leak constantly and have never had a problem. Warning, all the big stores I checked sell the same junk brands that are being phased out. I've had them leak out of the packaging before, but they usually start leaking after a few uses and need to be replaced. I found these last year and started using them instead and have never had a leak problem. I use them on my water filters, coffee makers etc so you can turn off the water to service them so they aren't just there for emergencies. From what I've found, these are the only ones you can actually use them with that don't leak after the first use or two.
