These appear to be good quality and fit properly. Used PEX clamps not crimp rings, and I got 100% good joints. I did find them same fitting type and size at a local plumbing supply. Do some price research.

Good

Very good crimp fit couplings fast delivery

Not correct size!

Good price and worked well.

I re-plumbed my very old craftsman home using these fittings. Each fitting worked perfectly wit zero leaks or defects.

Performed as expected. No issues and fast shipping

Not much to say, they are brass couplers. They arrived in good shape, none crushed or corroded. Worked perfectly where I needed them to. I would definitely buy these again.

Worked as needed

Good price and worked good.
