Bsp and npt fittings

[revans]

I'm from NZ where we use BSP fittings. However, I need to get the Bcarms schrader valve (or something similar) which I'm pretty sure would be NPT. http://www.bcarms.com/product_info.php? ... 8ac2850f05
I know the thread of bsp and npt fittings are slightly different, so is it alright to make a connection between the two or will it not be sealed enough? I will be pressurizing my chamber up to maybe 100psi with a bike pump, though I might try a little more if I ever get an air compressor. Cheers.

It says it will sort of work but you won't be able to fully thread it in and it will still leak. If you do go this route, you'll need a good amount of teflon tape. I would
A) find a BSP-NPT adapter.
B) buy a NPT tap
C)Use a schrader valve from bike tire and epoxy it.

Thanks, but I think I might have found an adapter here: http://www.autopia.co.nz/speco_access.htm (bottom) The bcarms schrader can fit into the npt side and my hose tail into the bsp side. should work.

I've used NPT 1/4" schraders in BSP fittings fine, not sure what pressure they can hold, but 100psi is no problem.
