Excelente aun no lo he usado pero luce como se describe

Air hose fitting supplied is incorrectly made and does not fit into the female hose end. It looks like a standard I/M fitting, but the fitting diameter is about 0.050" larger than a male I/M fitting, and this prevents it from fitting in, even with some amount of force applied. Further, the fitting connection into the regulator is not a standard NPT thread, but rather is a metric straight thread with o-ring. Consequently, you can't just replace the defective fitting with a new one, rendering the entire kit rather useless.

Works great

Needs a check valve or a ball valve to allow disconnecting air hose without losing pressure.Really pretty useless.

Very good diy product

Worked ok to check engine wish it was rated for a little more psi
