    High-Pressure Fill Valves for Air and Hydraulic Fluid

    Add air and hydraulic fluid to high-pressure struts, tanks, and hydraulic accumulators—these fill valves withstand pressures up to 5,000 psi. They meet MIL-PRF-6164, a military spec for high-pressure pneumatic valves used on aircrafts. Their stainless steel body resists rust in wet environments.
    Screw a coupler (not included) onto these valves to open them and let air flow in.
