Yellow Jacket 63334 Alloy Bending Mandrel 5/8 Inch

Product Description

The YELLOW JACKET 63334 is a 5/8-inch alloy bending mandrel designed for forming smooth, consistent bends in copper and soft metal tubing. Mandrels of this type are used to maintain tube roundness and prevent kinking or collapsing during the bending process. The 63334 is color-coded for quick size identification on the job, reducing the chance of grabbing the wrong mandrel when working through a set. HVAC and refrigeration technicians rely on bending mandrels when routing linesets, evaporator coil connections, and other tubing runs that require precise, clean bends without flow restriction.

This mandrel is suited for residential and light commercial HVAC work, refrigeration service, and plumbing applications where 5/8-inch tubing must be bent to a specific radius without deforming the tube wall. It is typically used in conjunction with a compatible tube bender to guide the tubing through the bend and maintain consistent geometry. Field technicians and apprentices alike benefit from the color-coded design when pulling from a full set of mandrels during system installation or retrofit work.

Key Features

• Sized for 5/8-inch tubing to maintain bore integrity through the full bend arc
• Alloy construction provides durability under repeated use and bending loads
• Color-coded exterior allows fast visual identification in a multi-size set
• Produces smooth, consistent bends that minimize flow restriction in refrigerant and fluid lines
• Designed to prevent tube kinking or wall collapse during the bending operation

Compatibility

Designed as an OEM-style bending mandrel for use with compatible tube benders sized for 5/8-inch outside-diameter soft metal tubing, as commonly used in HVAC and refrigeration lineset applications.

Installation Notes

Bending mandrels are installed by licensed HVAC technicians, refrigeration mechanics, and plumbers. Ensure the mandrel is properly seated in the bender before applying force to avoid off-center bends. Follow the tubing manufacturer's minimum bend radius recommendations to prevent wall thinning or cracking. Inspect the mandrel surface before each use and replace it if scoring or deformation is present.
