i've got the small radiators at last for my motorhome,

one of them is a bit of a bugger, the valves stick out the end past the cupboard it's mounted on, so i need to move the valve to under the rad, got the room, but need to find the best way to do this.

I know i could just get 2 15mm compression 90 degree angles and make a u bend up, but i was wondering if there's a u bend or 90 degree valve tail that screws directly into the rad? i imagine the rad threads are 1/2 inch bsp.. the tapered jobbies,

i basicaly want to move the valve connection around 180 degrees so it's under the rad and pointing the oposite way in as short a space as possible,

any suggestions?

I think the rad is parallel, just the mating thread is tapered.

For a tight turn, a 90deg threaded 'street' elbow looks like a good starting point, BES have them in stainless at less than I expected, 1.34 + vat (no chrome), code 14283 about a third of the way down this page:

one of the same would give you the return bend or there are spacers + female elbows on the next page if you need more room.

Quick (cheap) & dirty would be to remove the nut from a chrome compression elbow and mate the male end with rad. Gunked up with hemp & boss white this would set like concrete & not move, one of the silicone based pipe sealants (I use plumba thread) would do the same job but I would not use ptfe tape on parallel to parallel. Make the return bend with another chrome elbow. The benefit of this one is that chrome compression elbows are cheap & easy to get hold of.

Do you mean you're just after an angled TRV? If so they are used as commonly as straight ones. Eg look in here:

On that page there is an automatic bypass valve, and a differential pressure valve. What is the difference apart from the name and price?

BES should have something, but you might get away with using a

15mm compression elbow as an angled tail (since the thread for the compression nut is 1/2" BSP). Obviously the thread will be a lot shorter and you'll have to be an artist with your PTFE tape to get it mechanically and water tight (or maybe use one of those thread locking compunds like Talon?).
