The FIT-UP PRO Flange Spreader is a rugged, precision-engineered tool designed to safely separate pipe flanges during maintenance, installation, and inspection. It is suitable for flange diameters from 1 – 24″ / 25 – 610 mm and supports pressure ratings between 150 – 1,500 lbs / 68 – 680 kg. The tool features a hardened steel wedge that delivers controlled spreading action, reducing the risk of damage to flanges or surrounding components. With four available models (ST-301 to ST-304), spread pin diameters range from 5/8 – 1″, making it adaptable for various flange classes. The large feed screw allows smooth operation using either a 1 3/8″ wrench or a 1/2″ (12 mm) bar, ensuring flexibility even in confined spaces. Built with a compact, robust body for harsh industrial environments, this flange spreader provides repeatable, secure performance. It is a must-have for professionals who prioritize safety, precision, and durability in flange separation tasks.
