I have just recently begun to do sidewall fusions with one of your sidewinders. My previous experience with sidewall fusion was with electrofusion. I have been told that I must rough up the O.D. of the pipe and the saddle of the fitting. Is this true? If so, why?

Would you do this with electrofusion?

I have just recently completed a training class here at McElroy and we discussed this. yes you must rough the surface of the pipe and the fitting. It is recommended you use utility cloth with a grit of 50 or 60. NOT SANDPAPER or a file or a wire brush as these could leave contamination in the joint. The reason is to remove a small aount of material that may be contaminated or oxidized.

In my experience you do not rough the fitting as you could damage the wires. I have come to find in my short experience with my new McElroy machine that it is very economical. There are no problems with broken wires or any of the other problems that can arise from the electrofusion process.
