3/4 nominal copper pipe - 1.050" OD sch 40
 

I'm looking for a short piece (700mm long) of copper heavy walled pipe. I want to make up a section for the water pump to match the old piece and the easiest way is to thread 3/4BSPT and use a T piece I have.

I've got a load of 1" OD for when I replace it all the way through but I'll not get a full thread form.

Tried a few places but struggling to get anything other than 1" or metric. A google shows it's easily available in the states!
