Hi All, I'm having difficulty fixing my valves the right way up. I'm using 2 way valves and joining them together with SS tapered thread pieces, but I'm struggling to get them to line up when screwed together. Any tips or tricks on this aspect? The only way I can see to do it is to use a jointing compound. I'm currently trying Fernox LS-X which is silicone based, but I'm concerned it is not giving a solid join and in time the joints will move.

Can you take a pic to show what you mean by up the right way? I'm assuming you mean you can't tighten them far enough to get the motor (if motorized) or handle lined up where you want them. Tapered stainless steel threaded pieces are probably nipples? I'm not familiar with the Fernox.

There is a possibility that you are working with NPT (US National Pipe Thread) and BPT (British Pipe Thread) valves. You can make any scenario work. I used extra wraps of Teflon tape for my valve set ups and haven't had any issues. If you can't quite crank it to where you want to add a couple more wraps of Teflon tape and start it again, you'll get there.

Again, just assumptions here. A picture helps a ton

Good luck!!

I'm using 1/"2" BPT threads in the main. Here is one pic I have of a valve manifold. I have managed to get all three valves the right way , up, and while I haven't leak tested yet, and the pressure won't be great, I'm concerned that over tine the joints will come loose.

I would recommend using a hex nipple instead (www.buyfittingsonline.com/150-PSI-Stainl...ngs-Hex-Nipples.aspx). Get two hex wrenches with long handles and tighten down the valve holding the hex nipple and valve at the same time. The non-hex ones are too hard to tighten down without a special tool.

You could also get stainless specific teflon tape (www.buyfittingsonline.com/mill-rose-stai...-tape-1-2-x-260.aspx) which is a little thicker than the normal pipe tape.

Good luck.

I ended up using teflon tape in the end. They weren't perfect by any means, but near enough. It would have been nice to line them all up properly, but they all work and that's the main thing.

Thanks for the tips.
