Actually, if the thread's diameter is 0.5", it isn't any NPT or BSP thread. Also, if the thread's outer diameter is a meaningful quantity without any other qualifier, it isn't a tapered thread at all, but a straight thread.

The closest pipe comes to having a 1/2" diameter is 1/4" BSP pipe, which is .531" external diameter (plus or minus some tolerance, of course). 1/4" NPT pipe is a close second, at 0.540".

This site doesn't offer enough specifics on the thread to display any hint of knowing what they're talking about. I wouldn't recommend doing business with them.

It's likely to be 1/4" NPT, as this is the most common thread found on air compressor relief valves in the US.

Whoever designed that page appears to know nothing about pipe threads (Or pneumatic systems in general), so I'd heed DYI's warning and avoid purchasing from them.

Here are there pressure relief valves. Cost around £25. http://www.airlines-pneumatics.co.uk/webcat/Detprod.asp?ProductCode=S070140
