352-4010-21GSE is a ruggedized aerospace ground support equipment (GSE) tire inflation and pressure calibration tool, engineered to AS9100D quality standards and SAE AS5669 specifications, optimized for commercial aircraft ranging from narrow-body Airbus A320neo/Boeing 737 MAX to wide-body Boeing 777X/A350 XWB fleets during line maintenance and pre-flight inspections.

Fabricated from high-strength aluminum alloy with a weather-sealed IP67 enclosure, it delivers precise pressure regulation (0–300 psi, ±0.2% full-scale accuracy) and real-time temperature compensation (-40°C to 85°C). The tool integrates a digital LCD display, rechargeable lithium-ion battery (12-hour runtime), and quick-connect aircraft tire fittings, weighing 4.2 kg with dimensions of 280mm×150mm×100mm. Compliant with aviation GSE safety standards, it ensures accurate tire pressure setup, reducing landing gear wear and enhancing pre-flight operational safety for ground maintenance teams.
