Rc 1/2

Rc 1/2

(OP)
We have a radiator port that is specified as "dia. 35 Rc 1/2"  I'm not familar with this specification.  Can anyone tell me what it means and where I can purchase a fitting to fit it?

Sincerely

RE: Rc 1/2

Hello,

I think this is a matter of context. Perhaps some commas are missing from the specification?  The "dia." may refer to the term that preceeds it.  Thr Rc may refer to  a "Rockwell "C" scale" (and if so, you may be looking at a high grade hardened alloy steel (Rc 35 - 40)).  The 1/2 may be part of the following term.  That is my best guess.

Anyone else?

Regards, John.

Thanks John,

Actually, I finally got a bit information on it after some search through the internet.  It turns out Rc is an ISO thread code.  R is taperred male thread and Rc is taperred female thread.  1/2 is, well, 1/2".  This is of course based on British Standard Pipe Thread (BSPT, now that's a familiar term).  As for the dia. 35, I have no clue why it's there.  Thanks for you suggestion though.

sincerely
