Careful though, the orifice is probably very small - so for anything over 4.5mm you'll want to use this is a pilot valve for a QEV or piston valve rather than a main valve.

1/4 BSP is 19 TPI, 1/4 NPT is 18 TPI, so it sounds doable, but I couldn't trust the joint unless it was also secured with an appropriate adhesive.

Done!
I can not believe you can not do colors with SW.
There must be a way to do that.
