Review: This valve is works great. Very solid feel tuning on and off. No leaks. 😁
Review: I picked up a little shut-off valve and it’s been working pretty well for my water line project. It was easy to pop into place thanks to the push-connect design, which made things much faster than I expected. The only thing I found was that the plastic material feels a bit lighter than I thought, so I worry a little about long-term durability. Still, it’s done the job and I’d say it was a good buy.

## Questions & Answers

**Q: Cant find the right size! i need the threaded female end to be 3/8 npt and the tube end 1/4 od. can anyone help?**
A: This may or may not help you. But all tanks that have a small threaded outlet are 1/4" if you measure it it will actually measure close to 3/8 but they call it 1/4NPT. As far as I know they do not make a tank shutoff with 3/8NPT threads

**Q: So the outlet of this valve is a 1/4" id and 3/8" od correct?  So 1/4" pex will fit in the outlet as a press fit?**
A: No.  Pex is considered as the same size as copper. 1/4 pex is equal to 5/16" OD or 1/4 CTS

**Q: wjhich way does the valve point when in the on position?**
A: When the valve is open the blue tab is pointing to the fitting on the side, when closed it is 90 degrees to the fitting.

**Q: Will this work on a pureblueh2o tank? the tank looks similar with a 1/4" thread. that system uses a compression nut which is flimsy and leak-prone.**
A: These are classified as universal
