look up tom allen on here, he has air fittings of all kinds and should be able to sort you out.....chances are he will reply to this thread when he spots it
Yeah, those come with just about every macroline kit sold at any paintball website too. Of course, they're usually just advertised as 90* air fittings, you probably didn't get any results 'cause you were too specific.
Do you want the fitting with a female one end and a male the other.
Most of our fittings are 1/8 bsp, and either tapered or parallel. The difference between NPT and BSP is minimal so a BSP male to female elbow will probably do.
I have standard sized ones, or low profile elbows.
