J71038-1 is a precision aviation ground support equipment (GSE) accessory, compliant with AS9100D aerospace quality standards and FAA/EASA regulations, designed for commercial aircraft fuel system maintenance.

It acts as a specialized fuel tank cap torque tool, used during MRO work or pre-flight checks to tighten or loosen aircraft fuel tank caps. It delivers precise, preset torque to ensure the cap is secured properly, avoiding insufficient sealing that would cause fuel evaporation or contamination, or over-tightening that would damage the cap or the fuel tank's sealing structure, which could threaten flight safety or increase fuel waste.

Made from high-strength, corrosion-resistant alloy steel, it has an adjustable torque setting to fit different fuel tank cap sizes, and an ergonomic non-slip grip. Weighing 0.32kg, it is portable for on-aircraft or hangar use, critical for fuel system sealing integrity.
