Straight or tapered threads on concealed shower valve

[Richard1233]

I have a Victoria Plumbing concealed valve with 3/4" and 1/2" female inlets/outlets. I need to connect male iron 90 degree elbows (with compression fittings to the pipework). Should I use straight or parallel threads into the valve? I am thinking that I can use straight if I use Loctite 55 cord to make the seal? Any advice greatly appreciated.

Always tapered for me just be careful as you can overtighten things

Yes do what you are thinking ✅ .
Although have a serious think about sending it back and buying a decent one before it’s too late.

Thanks Shaun, just noticed that in the instructions for the valve it says not to use tapered for some unknown reason. But will Loctite 55 or maybe just PTFE tape be enough I wonder. Perhaps I will make up a few alternatives and pressure test them

Because people over tighten them and there so thin they crack the brass
