The Acrobat 160 low-force fusion machine from McElroy Manufacturing is designed for 63 mm to 160 mm polypropylene pipe. The machine can be configured from four to three jaws without tools. The narrow jaws allow fusions for flanges to outlet branches of tees and most fittings. Features include a hydraulic power unit and inserts for common butt-fused polypropylene pipe sizes and data logger to document key parameters. The facer and heater can be loaded from the top or bottom in the three-jaw configuration. 918/836-8611; www.mcelroy.com/fusion.
