Industrial 43-B Manual Die Necker

Beahm 43-B Manual Die Necker is a bench-top necking system that progressively reduces the outer diameter of cylindrical tubing by drawing it through a heated die. Its heated die uses thermocouple feedback for precise temperature control, and interchangeable dies determine the final neck diameter for repeatable neck-downs across multiple tube sizes. The unit is designed for manual operation with a 120 VAC supply and 100–125 PSI air pressure, with a heating range specified at 200–500°F. Some listings indicate this model ships without a die (“No Die”), so you’ll need the compatible Beahm interchangeable die kit; common applications include catheter shaft neck-downs, heat shrink tubing sizing, polymer tubing layering, and tubing jacketing.
