Product Description
The Dull Mandrel is manufactured from high-quality bearing steel with a chrome-plated surface finish. Available in various configurations including elliptical, semicircular, and thumb-shaped mandrels, it is designed for installation on U-shaped tube benders (return benders), long U-shaped tube benders (hairpin benders), or manual tube benders.
This precision tool ensures smooth, wrinkle-free bends in copper and aluminum tubes, producing full, bright elbows and hairpin tubes without scratches. Commonly used in manufacturing workshops for household air conditioners, automotive air conditioners, and rail transit air conditioners.
