Description:

intermediate pressure of about 140 psig. When diagnosing regulator problems, it's often very helpful to know if the IP is out-of-range. Slightly out-of-range values typically indicate the need for just a simple IP adjustment to compensate for wear. Significantly out-of-range values, particularly with "creep," often indicate a more serious impending high-pressure seat failure. Slow recovery time can indicate a clogged inlet filter. 
This compact, ultra-lightweight, intermediate pressure gauge is ready to go with you anywhere. It's perfect for helping diagnose regulator problems when you're away from the shop. Plugs into any standard BC low-pressure inflator hose.
