The Dual-Head Straight Chuck helps to air up Alcoa Dually Wheels and duallys where the valve stem is pointed towards the center of the vehicle. It can be swapped on to your Ventoso™ RED Tire Inflator Gauge in place of the standard HiPPO2, turning it in to a true multi-tasker.

Dualhead air chucks are used with dual rear wheels when stem extensions are not utilized. 

Angled back fits most dual wheels with steel wheels and some aluminum wheels with large openings. Straight back is primarily for aluminum Alcoa wheels with small round openings.  

We recommend the Safety Whip 2ft Hose Extension when airing up high pressure (80+psi) or potentially damaged tires. This gives 4ft of "Stand Away" safety in case of a tire blow out.
