Brass Push>Connect Air Brake Tube Fitting, 0.38 Inch Tube OD To 1/4-18 Male NPT, 45 deg Elbow

For typical air brake systems, 150 psi covers you just fine. Most commercial air brake circuits run between 100 and 125 psi under normal operating conditions, so this fitting has a reasonable buffer above that. It also carries DOT FMVSS 571.106 and SAE J1131 ratings, which are the compliance benchmarks specifically tied to air brake applications. You're not going to be pushing against the limits on a standard setup.

This fitting is made from CA360 brass, which is pretty durable, plus it's got an EP O-ring that can handle high temperatures and pressures. Should do the trick for your shop tools, provided you stay within its rated limits.

It’s made to accept 0.38 inch tube OD on the push-to-connect side and it has a 1/4-18 male NPT thread on the other end, with a 45 degree elbow to help turn the line in tight spots.
