J78002-186 is a precision aviation maintenance tool, compliant with AS9100D aerospace quality standards, developed for the maintenance of commercial aircraft engine bleed air systems.

It serves as a specialized bleed air line seal inspection gauge, used to detect micro-leaks or seal integrity issues in engine bleed air lines, which supply compressed air for aircraft systems like cabin pressurization and anti-icing. Accurate detection prevents air pressure loss that would compromise system function or flight safety.

Made from high-strength, lightweight titanium alloy, it features a sensitive pressure-sensing probe and a clear, calibrated display for quick reading. Weighing 0.57kg, it is portable for on-wing maintenance, and its compact design allows access to narrow engine sections. It is a critical tool for maintaining bleed air system reliability.
