Coilhose Pneumatics CH14-4 Brass Air Chuck 1/4 Fpt

Product Description

The COILHOSE PNEUMATICS CH14-4 is a closed check brass air chuck designed for non-gauged tire inflation and general pneumatic service work. The straight push-on design seats directly on the valve stem without threading, allowing fast, one-handed connection under pressure. The closed check valve retains air in the line when the chuck is removed, preventing pressure loss and reducing blowback. Constructed from solid brass, the CH14-4 is built for heavy-duty use and extended service life in shop or field environments. The 1/4-inch FPT inlet threads directly onto standard air hose fittings and inflator assemblies.

This air chuck is suited for tire service applications where non-gauged inflation is performed, including automotive, truck, and equipment tires. The straight push-on style is a common choice for high-volume inflation work at service bays, fleet maintenance shops, and portable compressor setups. The closed check design makes it a reliable choice for technicians who need consistent air retention between connections. It is compatible with standard 1/4-inch female pipe thread inflator hoses and manifolds used across the trade.

Installation Notes

Installation is performed by a qualified service technician or mechanic. Depressurize the air line before threading the CH14-4 onto the hose fitting to prevent uncontrolled air release. Apply thread sealant or PTFE tape to the 1/4-inch FPT male threads on the hose end before assembly. Verify all connections are tight and leak-free before returning the line to service.
