I need to make a joint with 2 parallel fittings, using an extended Parallel Nipple in between them. ( all in stainless steel )
Question: Will I have enough time to do it in one go? (Before it starts to go off i.e. lock up partially before I do the final twist).
Note I am using a 1mm shim in between the 2 fittings to get it to lock up in the right direction. I mention this as the shim is M16 so a little tight for bsp 3/8”. It rotates between the groves of the nipple, but does sit flat, when its rotated together, but is a bit fiddly - so not terribly quick to get right. Plus access is not particularly good, so not as quick as say doing it on a bench.
In the perfect world, because the parallel nipple is a little bit wobbly. It would be great if both sides of the joint were done in one go; because then, when the joint ‘locked together ’ it would effectively “pull“ the two fittings together, and seal the 2 fittings together perfectly (both the threads and the mating surfaces).
Or is It safer to do one side, wipe the joint clean and leave to set for 72 hours (the stated max cure); and then do the other side?
- Only negative of this method I can see is, it might set on the treads fine, but the angle of that mating surface might not be perfectly aligned to the other component.
More a question of practical use, i.e. will I have time (before it starts to cure off) to do that final tighten?
If done in one go, I was thinking of doing the joint into the small fitting say 1/2 a turn before it locks, then do the other side, and then do the final 1/2 turn to lock them together.
... only asking as I really want it done first time perfectly, to avoid an awkward clean up and redo.
Note:
So far I have had perfect results with this Loctite 577; except once when I backed off on joint half a turn, to align it, and it leaked slightly!
I also turned it a bit too far, on one other brass to stainless joint, hesitated and aborted. I noticed the clear light brown colour had started to go whitish by the time the joint was apart. It surprised me how fast it seemed to start going off Once it had some pressure.
