ABSTRACT:
A dry sprinkler installation and sealing device for a cold environment is disclosed. The dry sprinkler installation includes a supply conduit having a first end adapted to communicate with a fire retardant fluid source and a second end supporting a sprinkler head. The supply conduit is dimensioned to extend through an opening in a wall of a cold environment, e.g., a freezer ceiling. A flexible sealing device is positioned about the supply conduit adjacent an exterior surface of the cold environment. A first end of the sealing device is secured about the supply conduit and a second end of the sealing device is secured to an exterior surface of the cold environment. The flexible sealing device allows for radial and axial adjustments to the supply conduit and sprinkler head without compromising the integrity of the sealing device.
