The amount of people who don't properly seat a new O-ring before pressure testing is wild
Found a leak on a Cessna 172's hydraulic line yesterday, traced it back to a fitting someone just swapped. The new O-ring was in the groove, but it was twisted. You gotta lube it and rotate the fitting a full turn by hand to seat it right before you even pick up a wrench. Skipping that step means it pinches, and you get a slow weep that turns into a big problem. How many of you actually take that extra minute to do it?

Oh man, that's a solid tip. I've seen that exact twist happen, and it's such an easy fix to just spin it by hand first. @the_val, that slow leak makes total sense now.

Ugh, that reminds me of the time I cross-threaded a filter housing, @reeseanderson. You ever done something dumb like that?
