Hint: Try using a thin screwdriver to carefully loosen the packed residue by running it down the jaw serration grooves and then wire brush all upper and lower jaw serrations thoroughly. This will save on equipment cost maintenance, and ensure that PE pipe/fittings do not slip while performing butt fusion.The last thing you want to do is excessively clamp down, resulting in equipment damage (when pipe slippage is really caused by the lack of grip due to residue build-up). This will wear down the clamp knob and/or the jaw assembly, and replacement parts are very costly.
Have you ever struggled with trying to remove dirt residue from the jaw serrations?
Often times a wire brush doesn’t cut it because the residue gets caked up and is very hard to remove.
