Loctite 55

[cr0ft]

Is this stuff rubbish or am I just unlucky? Applied it to a 2" BSP joint as per the instructions. Each time it kept pulling out or jamming up the thread.

Tired 4 times in total before opting for PTFE instead. Job done..

Did you rough up the thread?
How many turns?

 

[ShaunCorbs]

Did you do it the right way / overlap the last strand

I would say unlucky

I use it on everything and its great gear, however I have never used it on anything as big as 2”

I think I might have been a doughnut and roughed up the grooves of the thread. I get the impression you're supposed to run the saw across the threads rather than along the grooves??

Anything better than a saw blade to rough them up? That will take forever on a 2" thread!

55 is good if it's a slack thread. For everything else I use 577 LOCTITE 577 Pipe Sealant - Loctite
In two years, ive had one 1" threaded fitting drip.

Every single threaded joint on this job, was done with 577 . Including the 2"

Ha, yes roughen the threads so the cord doesnt slip off.
2x hacksaw blades with a gaffa tape handle and scrape as your turn the pipe/fitting. 30 seconds job done

Don't use too much 55. It's tougher than ptfe and will just end up out of the joint. I split a 1/2" backplate elbow tightening a cranked bar shower fitting !

Will try that tomorrow scott_d. Just seems like there's no room in the thread for the sealant though. Had 4 turns going in, packet says 15 needed. Couldn't tighten it with 2x 2' stilsons!

Which merchants stock loctite 577 chalked please? With a 3 hour cure time I'd like to try it tomorrow for attempt 2!
