I'm working on a aluminum hydraulic tank for a dump trailer, (tractor trailer).
The originally installed nipple was stripped and leaked not bad but a decent size puddle after a few hours sitting.
So I bought a new nipple, threaded from both sides, cut it in half and that's when I discovered this issue, I stuck a pic of black pipe in the vice screwed on the aluminum nipple best I could, as in 1/2, 1-1/2 turns and that was with a pipe wrench toward the end. Definitely not like pitting regular black pipe together. Getting it apart was a nother battle.
I'm afraid to weld it to tank figuring the truck mechanics will never get their fittings screwed in, (and it's a 1st for new customer).
Is there a difference in the threading, threads or fifferent type thread pattern in aluminum visas steel?
