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.

Couplers for High-Pressure Fill Valves
Fill tanks and recharge struts—these couplers join hose to high-pressure fill valves with Schrader threads.
Some couplers meet SAE AS4395, an automotive industry standard for flared fitting dimensions.
70° elbow couplers are angled to access hard-to-reach valves.
Couplers with a shut-off valve let 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.

Air Chucks
Attach these chucks to your air hose so you can connect the hose to Schrader valves. Most often recognized from car and bike tires, Schrader valves are also commonly found on compressed air tanks and high-pressure hydraulic systems.
Chucks with a clip-on Schrader connection attach to the valve stem, so you don’t need to hold them as the valve fills.
Chucks with a sleeve-lock Schrader connection grab onto the valve by sliding the sleeve forward onto the valve. To disconnect, slide the sleeve back and pull out the valve.
Chucks with a threaded Schrader connection screw onto valves for a secure connection that you don’t need to hold in place.

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.
Valves with locking wire resist vibration to stay securely fastened.

Compressed Gas Fill Valves
Mount these valves onto compressed gas tanks. Also known as Schrader valves—which are typically used with compressed air—they have an internal spring that holds the valve shut when you depress the pin to add, remove, or check the pressure of compressed gas. Made of brass, these valves thread onto nuts more easily than valves made of harder metal. They also have good corrosion resistance. Valves have a thread cap to protect the stem from accidental gas release.
Valves for use with butane are commonly used on torches. They’re nickel plated for extra corrosion resistance.
Valves for use with nitrogen are often used in central heating systems.
