a portable assembly for securing a plastic fitting to a plastic pipe by employing fusion or thermal sealing is disclosed . the assembly is secured to the outer circumference of a plastic pipe at a desired location . the assembly can be secured at any longitudinal and lateral position along a plastic pipe . a heater heats both the pipe and the fitting to the point where they begin to melt . the heater is then removed and the fitting is pressed onto the surface of the pipe , thus fusing the fitting to the pipe . after cooling , the assembly is removed and the surface of the pipe within the interior of the fitting is drilled or removed . this now enables fluid within the pipe to be sent to the fitting and onto distribution lines which are connected to the fitting .
