PIPE THREADS/ BSP/ R Rp G

Post by patinwood »

I had commented under another heading and can now give a definite description.

R and Rp are compatible with BSP. R, Rp, and Rc threads are taken from BS EN 10226-3:2005 pipe threads where pressure-tight joints are made on the threads.
R,Rp and Rc are the same as BSPT (tapered threads).
G threads are taken from BS EN ISO 228-2:2003 pipe threads where pressure-tight joints are not made on the threads. The pressure tight joint is achieved by the compression of a soft material (such as an o-ring seal or washer ) between the end face of the male thread and a socket or nipple face, with a tightening of a back nut.
G is the same as BSPP (parallel thread).
I was missing the finer points!!
