its called (oddly enough )a heater tee

Kev, your memory's going. A heater tea used to have a male iron and female iron on the run and a compression on the branch. What he wants has compression ends on the run and a female iron branch.

I've got a new problem now

I measured the male thread on the PRV and it's 3/4". The pipes running through the tee are 15mm.

That pic I posted, and all parts like it, appear to pair a 1/2" or smaller female with 15 mm pass-thru.

What would be the best way to fit this all together? I can't find an adaptor to convert a 1/2" female to a 3/4" female which sounds like the simplest solution.

What would you do? Fit a 22 x 22 mm x 3/4" tee with adapters into the 15mm pipes? Fit a 15 x 15 x 15 tee, and then run a pipe section into a 15mm to 3/4" female adaptor (can compression fittings even withstand 6bar of pressure in a 15mm pipe?).

Why is this stuff never easy

I measured the male thread on the PRV and it's 3/4".

It may measure ¾", but it's actually ½". The size is nominal and refers to the bore of the pipe, not the OD of the thread.
