Coilhose Pneumatics A809 Closed Check Ball Foot Air Chuck

Product Description

The COILHOSE PNEUMATICS A809 is a closed-check air chuck designed for non-gauged tire inflation in professional shop and service environments. Built with a ball foot and clip-style chuck body in brass and steel construction, this unit delivers reliable sealing performance during inflation tasks. The closed-check design prevents air from escaping the chuck when it is not engaged with a valve stem, reducing waste and keeping inflation controlled. The 1/4-inch barbed inlet provides a straightforward connection to standard air lines. Its heavy-duty construction is intended for repeated use in demanding service conditions.

This air chuck is suited for tire service applications where non-gauged inflation is performed, such as in automotive shops, fleet maintenance bays, and mobile service operations. The ball foot profile allows the chuck to seat securely on valve stems, including those in tight or recessed wheel wells. The integrated clip holds the chuck in place on the stem during inflation, allowing hands-free operation. Service technicians, tire installers, and general automotive maintenance professionals are the primary users of this style of chuck.
