This invention relates to increasing the impermeability of the adapter plate contained by a spring brake actuator. This invention is associated with a new design for the guide section that allows the impermeability between the adapter plate and the push rod, each being a part of the spring brake actuators. With the rubber guide developed for the center of the adapter plate, the flexibility of the push rod passing through the center is enhanced; corrosions are eliminated; and simultaneously impermeability is achieved.
