Odd sizes

Where do the sizes 5/8, 7/8, 1 3/4, and 2 1/4 that are currently listed in the table come from? None of the British, German, European or ISO standards that I checked mention them. If nobody can provide an authoritative source for these sizes (e.g., some national standard), I'll remove them from the table. Markus Kuhn 10:11, 3 September 2006 (UTC)[reply]

Now removed.

Outer pipe diameter

Could you please provide a reference for the recently added outer-diameter inch figures? An ISO or BSI document preferably. BS EN 10226 does not contain any pipe dimensions, only thread dimensions. Therefore, also the term "Pipe size" is misplaced here, the standard says "Thread size". Markus Kuhn 16:36, 5 September 2006 (UTC)[reply]

Parallel/tapered

I want to know if it's possible to screw a tapered male thread into a parallel female thread, or vice versa. Someone must know this?IMacThere4iAm 09:35, 26 October 2006 (UTC) In the article:[reply]

Jointing threads: These are pipe threads for joints made pressure-tight by the mating of the threads. They always use a taper external thread, but can have either parallel or taper internal threads.

This means a male BSPT (tapered) fitting will seal happily onto a female BSPP (parallel).

Letter code

Any idea, where the letters G for parallel and R for tapered thread (as well as Rp and Rc) come from? Are these derived from some word in some language? Markus Kuhn 14:01, 10 February 2007 (UTC)[reply]

I'm not sure - we use BSPP and BSPT for _P_arrallel and _T_apered. 212.108.17.165 10:20, 2 April 2007 (UTC)[reply]

I later found the long and useful Wiki article on Screw Threads, which should be linked here. Clwydd (talk) 18:55, 21 July 2009 (UTC)[reply]
