We carry Intercomp tire pressure gauges because they are the most durable and shock-resistant in the industry, but many of our customers want one feature they don't offer: The ability to hold a reading when the gauge is removed from the tire. This compact check valve is all it takes to convert any of our analog tire pressure gauges to hold the pressure reading until the bleed valve is opened.
This little valve has 1/4 NPT female threads on the inlet end and 1/4 NPT male threads on the outlet end. Simply unscrew the hose on your Intercomp gauge from the bleed valve housing and install this valve between the two. Air will be able to enter the gauge, but it will not be able to exit until the bleed valve is opened. The valve adds about one inch to the length of the gauge assembly and does not affect accuracy. Brass housing with stainless steel spring.
Note: This valve is not designed for fluid applications!
