Coilhose® A831 CPAC-A831

Coilhose® air chucks are engineered and manufactured for Heavy-duty use and a long service life. Our air chucks are all made from solid brass. A chuck's valve check serves two purposes, it seals the chuck, closing the air passage while it is not being used and when used, it will open the core on the tire valve, allowing the pressure from the hose to be transferred to the tire. When a live air line is used for non-gauged inflation of the tire, a closed air chuck should be used. The open check chucks employ a check valve which will not seal the opening of the chuck when pressurized, however, it will open the core on the tire valve creating an open passage between the chuck and tire. Therefore, an open check air chuck should be used on an air line gauge in order to function properly.
