Abstract

An apparatus for fusing a pipe to a fitting includes an induction heating element wholly encased or coated with a flusible thermoplastic polymeric material, a fitting having a socket or a flange. The induction heating element is adapted to be inserted into said socket or mounted on said flange, the fitting and the element together defining a throughbore, a portion of a pipe adapted to be inserted into the throughbore or mountable on said flange. The apparatus also includes a locating and maintaining member on the induction heating element with one or more projections adapted to be snap-fitted on the fitting, the pipe or both, and capable of locating and maintaining the position of the heating element relative to the fitting or the member portion. The induction fusion element is capable of fusing the fitting and the pipe portion.
