UPDATE: DON'T BUY THIS HOSE! Rather, only buy it if you're using it for low pressures. MSC used the burst pressure as the working pressure spec. Working pressure is actually 300psi, so fine for something like an LP cocker running off an adjustable HPA turned way down. Screw-in tanks and Automags stay away. Credit to athomas for pointing out the issue and finding Eaton's spec:
Searched and didn't find and specific mentions of rated macroline, so here y'go AO. Eaton Synplex Solstice air brake tubing has a working pressure rating of 1200psi, costs $1.05/ft from MSC, and works perfectly with regular and CCM fittings.
