Coilhose Pneumatics CH15 Closed Check Brass Air Chuck

Product Description

The COILHOSE PNEUMATICS CH15 is a closed-check, lock-on air chuck designed for non-gauged tire inflation and general pneumatic service. Constructed from brass, it delivers reliable sealing and resists corrosion in shop and field environments. The closed-check design holds air in the line when the chuck is disconnected, reducing pressure loss and keeping the system primed. The 1/4-inch FPT threaded connection fits standard air hose fittings and inflator whips. Built for heavy-duty use, this chuck is suited to daily demands in automotive, fleet, and industrial settings where consistent, fast tire service is required.

The CH15 is intended for non-gauged inflation applications where a reliable lock-on connection is needed to seat and hold the chuck on a valve stem without continuous hand pressure. Typical install scenarios include tire service bays, fleet maintenance shops, and mobile service rigs. The lock-on design frees the technician to monitor inflation while the chuck remains secured to the valve stem, improving workflow and reducing the chance of accidental disconnection during inflation.

Key Features

• Closed-check design retains line pressure when chuck is disconnected

Compatibility

Designed as a replacement or add-on lock-on air chuck for standard pneumatic inflator whips and air hose assemblies with 1/4-inch FPT connections used in non-gauged tire inflation service.

Installation Notes

Installation is performed by a pneumatic technician or tire service professional. Depressurize the air line before threading the CH15 onto the inflator whip or hose end fitting. Apply thread sealant tape to the 1/4-inch FPT threads to prevent air leakage at the connection. Inspect the chuck and check valve for wear or debris before returning the assembly to service.
