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. Those for a 0.305”-32 thread size fit standard-bore Schrader valves. Those for a 0.485”-26 thread size fit large-bore Schrader valves. Do not use these air chucks with tire inflator gauges.
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.
Chucks with 2 outlets can be used at different angles and have an extended reach, so they’re ideal if your valve is hard to reach or in an awkward spot.

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.
