Unhappy Runtal radiator valve

I bought 2 baseboad runtal radiators and the valve from runtal. I put the pipes in and did the pressure test. I can't seem to not get a leak on the fitting. I tried with plumber tape and plumbing dope, but no luck.

is there a trick? Do i just need to try again until i get it right?
Also, is there a tool to tighten/un-tighten the fitting into the radiator.

Right now i used the whole valve, which allowed me to tighten it, but it won't allow me to un-tighten...

Thank you

I think you are talking about the part of the valve that threads into the radiator? Which the valve connects to with a 'union'?

Look inside that part, I think you will see that there is a HEX shape... you need to use a 'hex key', or 'allen wrench' to install that part. I'm guessing, because Runtal doesn't have the PDF files on line. Doesn't the instruction sheet tell you how?

You are correct, i'm talking about that part. There is no hex shape unfortunately. The plugs, for the unused connection holes, have a hex shape, but not the fitting. They have one line on each side protruding on the inside. I tried a screw driver, but it keep sliding off those line.

The instruction sheep just say to thread the fitting in and to make sure there are no leaks, no special instruction on how...

I'm betting it's a special tool then... bummer. If it was, you would think that someone along the line would mention it!

Ask your supplier? maybe even try a call to Runtal? Might end up having to _carefully_ use a small pipe wrench? I don't recommend it, but if you are careful, you won't mark it up too badly.
