left and right

how? "Any left- and right-hand tricks?"
The trick for left- and right-hand fittings and couplings is to get the correct bite the first time. The way to do that is to insert one side of the nipple/coupling and hand-tighten. Count the number of turns to get it to hand-tight. Then take apart and do the same on the other side. If one side took more turns to get it to hand-tighten, then add (or subtract) that number before starting; and turn that amount into the side that took more turns. In other words, the secret is to tighten the same amount after hand-tightening.

We hope that we have helped you on this page with nipples & fittings,
and thank you for helping to make PlumbingSupply.com the most famous Internet plumbing supplier.
