Air Fill Valves
Also known as Schrader valves, these valves rapidly fill or empty compressed air tanks or pneumatic tires.
Brass valves are softer than other metals, so they’re easier to thread together. They have good corrosion resistance. Nickel-plated brass valves have better corrosion resistance than unplated brass valves.
Stainless steel valves have very good corrosion resistance, so they’re the best choice for high humidity environments.

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-6164F, 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.
Valves with locking wire resist vibration to stay securely fastened.

Couplers for High-Pressure Fill Valves
Fill tanks and recharge struts—these couplers join hose to high-pressure fill valves with Schrader threads.
70° elbow couplers are angled to access hard-to-reach valves.
90° elbow couplers have a shut-off valve that lets you control the flow of air by hand. When used with Schrader valves that have a core, the core depressor pin in these couplers press valves open to let air flow in.
Flared couplers meet SAE AS4395, an automotive industry standard for flared fitting dimensions.

Air Compressor Air Flow Check Valves
Prevent air from escaping an air storage tank when the air compressor is not running. These valves install on the inlet of a tank. They open to allow airflow into the tank and close when flow stops or reverses direction. They have a 1/8 NPT tapped unloader port with removable plug for connecting to a pressure switch.

Pressure-Relieving Air Compressor Air Flow Check Valves
Release pressure in the line between a compressor and an air storage tank, making start-up easier on the motor. These valves install on the inlet of a tank to prevent air from escaping when the compressor is not running. They allow airflow in one direction and close when flow stops.
