Essential September 15, 2016
Reviewer: Drew Steeves from Kingston, ON Canada  
Throw out your other 1/2" nuts that aren't grooved: if they provide a good seal, it is by chance! Using these grooved nuts ensure that the 211 type o-rings (i.e., 13/16" ID) stay seated. You can tighten these nuts and not worry about the o-rings getting deformed due to the tightening pressure. Seals perfectly every time.
