Coilhose Pneumatics CH16S Brass Air Chuck Extension

Product Description

The COILHOSE PNEUMATICS CH16S is a closed check brass air chuck extension designed for use in compressed air inflation and service applications. The straight dual foot chuck design allows technicians to seat the chuck securely on valve stems during tire inflation or air pressure service work. Built with a closed check valve, the chuck holds pressure internally when disconnected from the air supply, preventing unintended air loss. At 0.25 pounds, it is a lightweight but durable fitting suited for shop and field use. The 1/4 FPT inlet threads to standard air hose fittings and inflation equipment commonly used by automotive, fleet, and industrial service technicians.

This chuck extension is well suited for automotive, truck, and equipment service environments where consistent valve stem engagement is required. The straight dual foot configuration provides stable contact on standard Schrader-type valve stems. It is commonly used at tire service bays, fleet maintenance shops, and general compressed air service stations. The closed check design makes it practical for applications where maintaining line pressure between inflation tasks is a priority.

Installation Notes

Installation is performed by depressurizing the air line before threading the CH16S onto the hose end fitting. Hand-tighten the 1/4 FPT connection, then confirm with a wrench to seat the threads without overtightening brass fittings. Verify there are no leaks at the connection before returning the line to service. This fitting should be installed and serviced by a qualified technician familiar with compressed air system safety practices.
