I need some bronze tubing to replace one of the spigots on my water pump. It's 13.5mm OD and 2mm wall thickness. 33mm long. Any idea where I could find it.

Last time I was involved in something similar, the difficult thing turned out to be cutting the taper thread.

You'll could purchase some hex. drawn bronze from say a model engineer supplier and have it machined up, (expensive route). Or, assuming a BSP thread, buy a DZR brass straight male hose tail from ASAP. (1/4" BSP to 13mm hose at a guess? which is ~£1.50 ), and some Loctite sealant.

That's a brilliant suggestion. Thank you.

Slight problem, the hose tails from ASAP are BSPP (parallel thread), I need BSPT (taper thread). I could probable get one re-cut though.
I've learned all sorts about thread types with this enquiry like tapered male will fit into parallel female but not contrarywise.

By all means look for a taper thread, but I wouldn't get too hung up on it. A parallel thread with a good thread sealant will be just as good IMHO, (assuming it fits your pump thread).
Getting a thread re-cut might not be so easy. Taper dies cost a fortune, you need a very good reason to buy one in the first place.

The thread in the pump body is tapered.

Thanks David, their website shows various sizes but not 1/4" bspt male to 10mm hose. but it does show 1/4" bspt to 32mm hose! I've sent them an email.
