Dual air chuck fits standard automotive-style stem valves and can be used to fill a variety of tires, including bicycle tires. 

The angled chuck has 2 connection points and extends 11"/274mm, so it can access hard-to-reach valves. 

A built-in shut off valve stops airflow when the chuck is not in use.
