The Load Pressure 0 To 150 PSI Gauges are a practical and reliable solution for monitoring air bag pressure. With a gauge that reads 0 to 150 PSI, it accurately displays the pressure on the air bags. The built-in high accuracy PSI sensor ensures precise readings. Available with a choice of red, blue, or green LED display and black or chrome bezel, it seamlessly fits into a standard 2 1/16 inch hole. Made in the USA, this gauge is compatible with most Peterbilt models 2005 and older, as well as other models excluding Kenworth.
