Air Chuck Dualhead Chuck Straight Back Plug Power Tank. Dualhead Chuck with straight back and straight forward. Heavy construction with chrome finish. Comes with an industrial plug. Normally open chuck which means it does not hold back air pressure so it must be used with a valve or with our tire inflator.
This straight back is most commonly used on Alcoa aluminum wheels with small holes there the chuck must fit into the small hole and pulled straight back onto stem.
