Does anyone know what this thread is?



I have a MK 1 S200 and the cylinder has a 1/8th BSP male that allows the old style "Poppet" valve to screw onto. I want to change it for a T bar type, as I have to take the silencer off every time to fill it, which is a ball ache.
Best fittings dont know what it is neither.

I'm going to have to make a female to female adapter to make it work

Unless anyone knows of a 1/8th BSP Foster type valve....
