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 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.
