A door closer with a plastic (nylon) plug in an aperture in the top of the door closer body. In the event of a fire, as the door heats up, the door closer body also heats up. When the temperature of the door closer reaches approximately 250° F, the hydraulic fluid within the door closer will begin to emerge from the plastic plug area and spills over and collects in the top of the door closer body casting which forms an open surfaced fluid retaining reservoir. The contained fluid smokes and evaporates from the heat. No fluid escapes down to the door and the floor. This reduces the chance of causing a fire on the non-fire side of the door and frame.
