SUNJOYCO 6-in-1 Swage Tool HVAC Set with Bit Holder – Copper Tube Expander 1/4 to 7/8 in

Overview

Meet the SUNJOYCO 6-in-1 Swage Tool HVAC Repairing Set, a compact kit designed to handle copper and aluminum pipe expansions across six common sizes. It can connect directly to most electric drills, helping you move from prep to flare without swapping tools.

The six swage sizes span 1/4", 3/8", 1/2", 5/8", 3/4" and 7/8", giving you options to match standard refrigerant lines and metal tubing. This flexibility can save you time on job sites and reduce the number of tools you carry.

Durable design and precise performance

Constructed from high-quality HSS steel, the tool emphasizes durable hardness, wear resistance, and a strong elastic limit. The rotating expander creates a uniform flare, promoting reliable, leak-aware connections when paired with proper PPE and a steady drill speed.

How to use

Attach the swage tool to a drill, select the appropriate size, and rotate the expander to widen the copper tube. Use a moderate, steady speed to help ensure a consistent flare and a clean finish.

Convenience on the go

The built-in bit holder keychain keeps 1/4" hex shank bits nearby, while the compact form fits into a tool bag or pouch. This makes the kit practical for field work and service calls.
