Coilhose Pneumatics A807 Open Check Brass Ball Foot Air Chuck

Product Description

The COILHOSE PNEUMATICS A807 is an open-check brass ball foot air chuck designed for non-gauged tire inflation. The ball foot design locks onto the valve stem and holds air pressure during inflation without requiring the technician to hold the chuck in place. Constructed from brass for durability, this chuck is built for heavy-duty use and long service life. It connects via a 1/4 inch barbed fitting, making it compatible with standard air hose assemblies. This chuck is a common tool for tire service in automotive, fleet, and commercial tire shops.

The A807 is suited for non-gauged tire inflation applications where a reliable, hands-free connection to the valve stem is needed. The open-check design allows airflow through the chuck when engaged with the valve stem. Ball foot chucks are a standard choice for service bays, truck stops, and fleet maintenance operations where technicians inflate tires frequently throughout the day. The 1/4 inch barbed inlet fits directly onto standard air hose barb fittings.

Installation Notes

Installation is performed by pressing the ball foot chuck onto the tire valve stem until it seats and locks. Before servicing, ensure the air supply line is depressurized before attaching or removing the chuck from the hose barb fitting. Use appropriate thread sealant or hose clamps on the barbed connection to prevent air leaks. This chuck is intended for tire inflation service only and should not be used for applications outside its rated design.
