98V06001000000 is a specialized aerospace engine oil system pressure testing tool, compliant with AS9100D quality standards and FAA/EASA MRO regulations, designed for CFM56 series turbofan engines. It is used to test the pressure tightness and stability of the engine's lubricating oil system during maintenance, identifying potential leaks, seal failures or pressure abnormalities that could reduce lubrication effectiveness, cause component wear, or lead to oil system damage.

Made from high-strength, corrosion-resistant stainless steel with a high-precision analog pressure gauge, it operates stably in -15°C to 105°C workshop environments. Weighing 0.69kg with a quick-connect interface, it delivers testing accuracy within ±0.25 psi, simplifying the oil system inspection process. It is an essential tool for engine lubrication system MRO work.
