ABSTRACT:
A fire protective collar for plastic fittings used in flammable fluid handling equipment is formed in two pieces which fit together around the fitting. Each piece has a semicircular top with a cutout for fitting around a pipe, and semicircular walls for fitting around the fitting. At the ends of each wall is a flange with a hole so that the two pieces can be removably fixed together by bolts and wing nuts. The collar may be used in a system where a containment box for collecting leaking gasoline from gasoline handling equipment, such as a gasoline dispenser, is disposed below the dispenser. The box receives a gasoline supply pipe passing through an aperture, and a fitting is provided for sealing the aperture and adjustably fixing the supply pipe. The fitting includes a main body, a deformable element, a seating piece for seating the deformable element and threaded to the main body, and a clamping piece threadable onto the seating piece to cam the deformable element radially inward to contact the supply pipe. In another embodiment, the main body and seating piece are combined unitarily. The box has another aperture through which a conduit passes, and there is a universal fitting for sealing that aperture. The box has a further aperture for communicating with a vapor recovery pipe, and there is another universal fitting identical to the first for connecting with the pipe. Collars may be used for the universal fittings as well as the fitting for the supply pipe.
