This is a versatile nitrogen service tool. The Strut (wing) Leveler was developed because of calls from the field for the need to charge both left and right main landing gear at the same time to easily get them to the same level. The two high-quality cartridge valves, (Control and Pressure Release), are rated at 3000 psi. It comes with standard AN-4 flared fittings, a high-pressure service valve, and a 1500 psi gauge. Lower pressure gauge models-200 psi and 800 psi are optional. Custom rated gauges are available on request.
