The updated CLT-2PB Cylinder Leakage Tester from A&E Hand Tool incorporates an industrial interchange quick coupler connection which allows it to be used with most standard compression test adapters on the market. The two gauge design allows for monitoring of input air-line pressure to ensure accurate testing. Both gauges are larger, easier to read and incorporate a redesigned gauge boot for added protection. An easy to use regulator allows for precise control of input air pressure.
