GLADHAND WITH BUILT-IN DIRT PROTECTION PLUG

摘要

GLADHANED WITH BUILT-IN DIRT PROTECTION PLUG A combination gladhand and dirt protection plug includes a gladhand body with a chamber within the body. There are a pair of air ports in communication with the chamber, with one of the ports functioning as an air inlet. A seal is positioned in one of the air ports and there is a dirt protection plug movable in the chamber toward and away from the seal to open and close said one port. Spring means are positioned within the body and bias said plug toward a port closing position. Said plug has a surface in communication with the air inlet, with air pressure at the inlet, applied to said surface, causing said plug to automatically move against said spring and away from said seal to an open position.
