Polygon LT

20mm - 110mm (½" - 3 ½")

McElroy’s Polygon™ is the premier lightweight solution for fusing polypropylene pipe and fittings. This line of compact fusion equipment is DataLogger® compatible, allowing operators to capture joint information and ensure that proper fusion procedures have been followed.

Based on the design platform and operation of the original Polygon, the Polygon LT provides a fast open/close time for butt fusing 20mm to 110mm pipe thanks to a specially-designed drive screw that allows for multiple inches of carriage travel per drive wheel rotation. With shortened parts to maximize a compact design, it’s capable of providing up to 250 psi fusion pressure and includes a smaller heater and facer to accommodate for the smallest of pipe sizes. For low pressure butt fusion, it includes a new internal spring and shaft brake that allows for precise control and gives operators the ability to lock the machine in place.
