Plastic “brass” instruments have been in the marketplace for a few years now.
First came the trombones, then the trumpets.
Now manufacturers are taking what they’ve learned and applying it to more ambitious designs such as the plastic tuba.
Cool Winds is at the forefront of this design and manufacturing revolution.

Closed Flow: closed flow air chucks feature internal “check valves” that do not allow air to flow to or from the chuck unless the chuck is engaged with a tire valve stem, which makes them more efficient for using directly on an air compressor hose line, since they will not rapidly deplete the air tank unless engaged with a tire valve stem.
Easy to Use: pushed forward the sleeve to lock the valve stem and pulled back the sleeve to release the lock on air chuck, it makes things easy that you can use one hand to seal and release the chuck.
Standard Size: the top thread, 1/4 Inch FNPT.
Heavy Duty: the lock on air chuck, made of steel and zinc, can prevent rust.
The inside three claws are metal plating to protect them from oxidation.
Wide Use: the top thread is standard size 1/4 inch FNPT, fit for most tire inflator air compressor, air accessory kit, air compressor accessories, inflator gauge compressor accessories.
