A sealing assembly (10) for use in sealing, eg, an end of an indirect heating coil to a wall of a hot water tank, the assembly (10) having a tubular body (16), externally threaded, a flange (17) at one end of the body (16) and a complementary nut (18) having an internal recess (19). The body (16) has, at the transition to the flange (17) outwardly extending projections (20) which, in use, engage and deform the metal of a wall of a tank to restrain the body (16) against rotation upon tightening of the nut (18). <IMAGE> |
