Worst product ever.

Would Not Recommend

Bought this after getting horrible help at Lowe’s. Despite Teflon tape and pipe dope, they leaked. Returned one. The other did not get return. But it leaked weeks later. Lost receipt at that point so I ate one of these overpriced, worthless valve.

Perfect coupling for ice maker water line.

Would Recommend

This was exactly what I needed to make my ice maker water line work off of a fitting connector to my toilet water supply for the ice maker in kitchen.

B&K 3/8-in Compression x FIP Adapter Coupling

I bought these fittings as I was repairing the ice maker line on my 28 year old refrigerator. I am 100% satisfied with the performance of this fitting as a transitional piece from copper to poly tubing.

Not for old hardened copper lines

Would Not Recommend

The crimp ferrule is only one tapered on one side and the ferrule nut does not have enough threads to provide the force require to crimp the ferrule without stripping. I ended up buying a double taper sided crimp ferrule and a separate ferrule nut with more threads. They say the third time is a charm. Well it was in this case.
