Yeah, those fittings are "quick fittings" for 1/4" flexible hose (I use air brake hose for 18 wheelers). The threads for the fittings are 1/8" NPT. You can pick these up for cheap at McMastercarr.com or any Peterbilt/Kenworth truck parts place. The big rigs use DOT approved fittings but we can get away with regular fittings (good for up to 200 psi). The sliders are being used as air tanks, although not really huge volume but better than nothing.
