Alloy Ratchet Tube Bender Kit, Quick Change Bending Mandrels

Yellow Jacket 63331 – Alloy Ratchet Tube Bender Kit for Soft Tubing

The Yellow Jacket 63331 Ratchet Tube Bender Kit is designed for precision bending of soft copper, aluminum, and light-wall hydraulic tubing. Engineered for field and shop use, the ratcheting mechanism provides mechanical advantage, reducing operator fatigue while maintaining accurate, kink-free bends.

This kit includes interchangeable mandrels to accommodate six tubing sizes from 1/4" to 7/8". Quick-change bending shoes and mandrels allow for efficient transitions between sizes without disassembly. The compact ratchet handle is designed for confined spaces, making it suitable for refrigeration, HVAC, and plumbing work in retrofit or new construction applications.

Usage Notes

This bender kit is suitable for use in HVACR installation, refrigeration line fabrication, and plumbing systems where field-formed bends are required. Proper alignment of tubing and mandrel, as well as consistent force application, are necessary to ensure bend quality. Users should be trained in tubing handling to avoid collapse or flattening during the process.
