351-7000-01GSE is a precision-engineered aircraft hydraulic pressure test gauge, compliant with AS9100D aerospace standards and SAE AS4735 specifications, designed for Boeing 737 MAX and Airbus A320neo hydraulic system maintenance.

Crafted from 316L stainless steel with a scratch-resistant sapphire lens, it measures pressure ranges of 0–5000 psi with ±0.1% FS accuracy, covering landing gear, brake, and flight control hydraulic circuits. Weighing 0.8 kg and featuring a 1/4-inch NPT hydraulic quick-connect fitting, its ergonomic handheld design enables one-handed operation in tight aircraft bays. With a backlit LCD display and a battery life of 200 hours, it functions in temperatures from -40°C to 85°C, making it an essential ground support tool for MRO technicians to verify hydraulic system integrity and ensure aircraft operational safety.
