Claim 16:
17. A spring air brake actuator system for heavy duty vehicles, wherein the actuator system comprises external venting of the emergency brake housing, comprising: an actuator housing, a service diaphragm, a service pushrod, a service spring, a parking diaphragm, a parking push-rod, a parking spring, a caging tool opening, and a plug for the caging tool opening that separates air from water while allowing air to exchange between the interior and exterior of the actuator housing, wherein the plug comprises (1) at least one vent mechanism comprising at least one through-hole that services gas exchange for the actuator housing, (2) at least one shelter of the vent mechanism distal from the actuator housing that provides at least one sheltered area distal to the vent mechanism, (3) at least one area-enclosing annular abutment rising distally from the actuator housing and annularly enclosing at least the at least one shelter and at least a distal portion of the at least one vent mechanism, (4) at least one fluid-exchange passageway within the at least one shelter allowing fluid exchange between the at least one sheltered area and the at least one area-enclosing annular abutment, wherein fluid exits the at least one sheltered area via movement through the at least one fluid-exchange passageway and exits the device by moving over the at least one area-enclosing annular abutment and (5) at least one base member integrated with said at least one area-enclosing annular abutment, wherein said at least one area-enclosing annular abutment rises distally from said at least one base member, said at least one base member comprising at least one base-member through-opening integrated with the at least one vent mechanism to allow gas exchange between the interior of the housing and the exterior of the housing through the at least one through-hole of the vent mechanism and comprising at least one attachment mechanism for attachment of the device to at least one opening in the at least one housing.
