Surest way to connect to wall plate elbow?

[paul alan]

Hi I have installed my concealed shower valve and fitted wall panels, I'm soon ready to put shower fittings through the panels and screw them into the wall plate elbows.

My question is what shall I use to seal the threads in the most effective way?

I have Loctite thread locker as the thread needs to be just shy of bottoming out into the elbow to be in the position it needs to be, but when I tested this initialy before I tanked the walls and put the panels in place I had a small weep on one of the joints.

I wound the thread locker around the 1/2" thread 8 times as per the instruction.

I also have plumbers mate and PTFE.

Would a combination of these products offer more reliability?

Any advice greatly appreciated.

Plumbers mait isn’t for this scenario. You could use a jointing compound, just make sure it’s suitable for potable water.

There seems to be a few different options, do you have any recommendations?

How about the liquiD PTFE types?

Thanks

Jet blue is supposed to be good, I only used it once several years ago, so no idea what it’s like now. Water Hawk by Fernox is ok, but messy. You could use the Loctite and apply a little more? Did you apply it right?

I think so, the dispenser said 8 threads per 1/2" pipe. Honestly I might have put 9-10 but was mindful of not splitting the elbow so didnt want to use more.

I wound them diagonal to the thread in a random but consisitent pattern, one joint was fine but the other had a slight weep so naturaly I've lost a little confidence in the product.

If you put it in the groves of the threads and I know it sounds silly did you do it in the correct direction eg putting it on so it doesn’t unravel when tighting

 

[paul alan]

I think so, I held the fitting in my left hand and wound the thread locker on with my right anti clockwise?

 

[ShaunCorbs]

yes that’s correct

Did you roughen the male threads first? It helps stop the PTFE/tape/Loctite 55 fom sliding off.

Also, what type of Loctite are you using?

 

[paul alan]

No, ddint roughen them up.

Im using loctite 55 I think, its a thread coming from a small dispenser with a cutter.

Jet blue and ptfe tape are my go to.

Picked up some water hawk today, so I'll use that on the thread then wrap it with the loctite and hope to god it never leaks!
