Tapered thread size on heater valve

[buzzer]

A quick question if anyone knows. I am fitting my TC out and have fitted a racing type 47 exhaust system from Banks and I want to keep the heater in place so I want to fit the heater valve. The heater valve won't fit onto the head with the exhaust system in place and I need to fit a 90 degree male/female bend to get it to fit. the thread on the heater valve looks like a BSPT  British Standard Pipe Thread Tapered to me, but does anyone know what the thread size is?

Thanks

I had a similar problem and I used a 3/8 NPT 45 degree elbow. NPT is a tapered thread and is common on this side of the pond for pipe applications so BSPT and NPT must be very close. I got mine from Earls Supply but a good supplier of AN plumbing should be able to sell you one. You might be able to get one at a hardware store but I wouldn't put one on my car!

NPT fittings are commonly available in steel and brass, and from specialty suppliers in alloy.  Your local hardware store will have 'em.

As a reference the thread on the heater valve us 3/8" BSPT, British Standard Pipe Thread Tapered.

No luck in hardware stores, Ebay was the answer.  I must admit I was shocked at how little staff in even the specialist hardware stores know, BSP...what's that from a local trade stockist. must have visited them the wrong time.  I found the same with nuts and bolts, basically anything above 12mm is specialist and if you want UNC ..forget it! EBay has been my saviour.

 I was going to suggest you try Think Automotive, but it sounds like you're already sorted. They're pretty good at car plumbing for most fluid types

Yes, sorted but my challenge is I have too many other time pressure jobs..and work to do so the i'm not making much progress at the moment.
And I have to do my books this week for my accountant AHHHH
