Coilhose Pneumatics CH15A Lock-on Brass Air Chuck

Product Description

The COILHOSE PNEUMATICS CH15A is a lock-on style air chuck with an open check valve, designed for inflating tires and other non-gauged pneumatic inflation tasks. Constructed from solid brass, it delivers the durability and corrosion resistance expected in heavy-duty shop and field use. The 1/4-inch FPT threaded connection makes it straightforward to attach to standard air hose fittings and inflation lines. Lock-on engagement keeps the chuck secured to the valve stem during inflation, freeing the technician's hands and reducing the chance of accidental air loss mid-fill. This chuck is built for long service life under repeated daily use in automotive, fleet, and tire service environments.

The CH15A is suited for automotive shops, fleet maintenance bays, tire shops, and mobile service applications where reliable non-gauged inflation is needed. The open check design allows free airflow through the chuck body when engaged with a valve stem, supporting consistent, unobstructed inflation. The lock-on mechanism eliminates the need to hold constant pressure against the valve stem, making it a practical choice for technicians working through high daily tire service volume.

Compatibility

Designed for non-gauged tire inflation applications and compatible with standard 1/4-inch FPT air hose fittings and inflation line assemblies.

Installation Notes

Installation is performed by a technician or mechanic familiar with compressed air systems. Depressurize the air line before threading the chuck onto the hose fitting to avoid injury. Use appropriate thread sealant tape on FPT connections and tighten to a firm hand-tight fit, then snug with a wrench — avoid overtightening brass fittings to prevent thread damage. Inspect the valve stem and chuck seat for debris before each use to maintain a proper seal.
