Product Description
The One-Way Mandrel is engineered from high-quality bearing steel and features a hard chrome electroplated surface for superior performance and durability. Its ball head swings in only one direction, making it ideal for small U-tube bending machines used to bend copper and aluminum elbows.
This mandrel ensures perfectly smooth finished elbows with no wrinkles or scratches, making it essential for refrigeration and heat exchange applications. Available in standard diameters from Φ4.76 to Φ19.05, with custom sizes available upon request.
