"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 offer many thoughts (quotes) to ponder, such as:
"A string of excited, fugitive, miscellaneous pleasures is not happiness; happiness resides in imaginative reflection and judgment, when the picture of one's life, or of human life, as it truly has been or is, satisfies the will, and is gladly accepted." - George Santayana
