MASTER ORIFICE TOOL (ATS)

The Master Orifice Tool is required by Continental’s SB03-3 Service Bulletin. Use it with Eastern’s E2, or our own 2E Differential Pressure tester to determine your calibrated leakage reading prior to engine testing. Precision machined from non-sparking brass. Note: this tool is not needed by our 2EM or Eastern’s E2M, as they already have their own built-in master orifice.
