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

Angled back fits most dual wheels with steel wheels and some aluminum wheels with large openings. This model comes either “closed” or “open”. The closed chuck holds back air until you push it onto a stem. The open version is required when attached to a tire inflator like our Ventoso RED tire inflators.

Angled back also works great for spoked wheels like on motorcycles. 

Straight back is primarily for aluminum Alcoa wheels with small round openings.  This style is only available in “open”. Therefore, it can be used with our Ventoso RED tire inflators.

All have common ¼npt female threads. 

If ordering to add to your Ventoso RED tire inflator don’t forget to Add a ¼ Industrial Plug.
