I needed two sizes of nuts for a brake line I was replacing. I bought a separate bag of both sizes and a tube of nuts from 4LIFETIMELINES. Nuts in separate packages like this one didn't fit as well as the nuts in the kit that were listed as the same size and thread. These bags were much sturdier and the hand threads didn't tighten very much whereas the ones that came with the kit hand tightened before requiring a wrench to tighten them. This fitted the new hose and could be tightened with reasonable force. I tried it on an existing hose that had a bit of rust on the lip and it took a lot of effort to turn it right away so I didn't push it. Complete fittings fit well on both hoses. I will look into another brand for future purchases.
