An improved version of our #43270 Deluxe Regulator Tester, this device will attach to virtually ALL common BC (and alternate regulator/inflator) hoses, allowing the technician to sample the regulator's staging (intermediate) pressure (IP). A quick coupler on the bottom of the unit provides interchangeability for three adapters, each of which unites with a different type of BC hose. Simply select the matching adapter for the particular BC hose, snap it onto the Tester, attach the BC hose, and check the IP. A fourth adapter allows the regulator's second stage hose to be attached directly to the tester to ferret out those elusive first stage leaks, pressure creeps, or erratic lockup behavior without the presence of the second stage or other potential interference. The Tester features a 300 psi liquid-filled gauge with a 4" stainless case for general durability and resistance to shock from rough-handling and rapid pressure-cycling. A 200 psi over-pressure valve protects the gauge from sudden, unexpected pressure surges. A pushbutton bleeder allows rapid cycling of the staging action for conducting quick, multiple IP tests and then final depressurization.
