Good but Soft

Quality is good but copper is soft so don't overtighten. Works well for sealing.

No More Leaks

Solved my leaking issue immediately. The flange distributes pressure nicely.

Excellent Quality

These nuts fit perfectly on my water tank inlet. The copper is thick and doesn't strip easily.
