Coilhose Pneumatics A810 Closed Check Brass Ball Foot Chuck

Product Description

The COILHOSE PNEUMATICS A810 is a closed check brass ball foot air chuck designed for non-gauged tire inflation in professional and shop environments. The ball foot design clamps onto the valve stem and holds securely during inflation without requiring continuous hand pressure. Built from solid brass for heavy-duty use and long service life, this chuck connects via a standard 1/4-inch MPT fitting. The closed check valve retains air in the hose when the chuck is disconnected, reducing blowback and air loss. Licensed technicians, fleet service professionals, and tire shop crews use this type of chuck in daily production workflows.

The A810 is suited for automotive, truck, and light equipment tire service where hands-free inflation is required. The ball foot chuck style is the standard choice for non-gauged inflation tasks, where the technician sets pressure using a separate gauge or regulator. This chuck threads directly onto a standard 1/4-inch MPT fitting on an air hose end or inline adapter. It is appropriate for both shop floor use and mobile service applications.

Installation Notes

Depressurize the air line completely before removing or installing any chuck or hose fitting. Thread the A810 onto a 1/4-inch MPT hose end fitting by hand first, then snug with an appropriate wrench — do not overtighten brass fittings. Apply thread sealant tape to the MPT threads as needed per shop practice. Verify there are no air leaks at the connection before returning the line to service.
