Dual Head Air Chuck - Straight Forward, Angled Back Power Tank GX470 It stretches up to 30Dualhead 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.
