GlowShift’s Black 7 Color Series 200 PSI Air Pressure Gauge is essential for any vehicle that has air brakes or an aftermarket air suspension. This mechanical air pressure gauge reads from 0 to 200 PSI with the included 1/8-27 NPT male fitting that is located on the back of the gauge. You’ll also have the classic look of an analog gauge with an illuminated red needle that sweeps 270 degrees and choice of a blue, green, yellow, purple, red, teal or white LED display on a Black gauge face.
