HENLYNX Manual Copper Tube Rounder — 6-Size OD Range for 1/4 to 7/8 in ACR Copper, Aluminum & Steel Tubing | HVAC & Refrigeration

HENLYNX Manual Copper Tube Rounder: Precision Tool for HVAC, Refrigeration, and Plumbing

The HENLYNX Manual Copper Tube Rounder is a professional-grade solution for restoring damaged tubes to their original roundness. By applying uniform pressure through specially designed jaw cavities, it helps create smooth, round ends that support reliable, leak-free connections in a variety of systems. Rather than replacing an entire section, technicians and DIYers can often salvage tubing and complete a job more efficiently.

Key benefits at a glance

• Six outside diameters supported: 1/4, 3/8, 1/2, 5/8, 3/4, and 7/8 inches, covering common ACR copper tubes and soft metals.
• Works on ACR copper tubing; also effective on soft aluminum and thin-walled steel for broad compatibility.
• Ergonomic lever and compact jaw head deliver leverage and precision in tight spaces with minimal effort.

How it helps on the job

Whether you're repairing a central air system, a refrigerator line, or a custom plumbing run, this tool provides tactile feedback and consistent results. The action is manual, so you feel the tube as it rounds, helping you avoid over-crimping.

• Save time by restoring curved ends without full tube replacement.
• Save money by salvaging tubing from existing lines and assemblies.
• Achieve a consistent circular profile to improve fit and seal integrity.
• Operate comfortably for longer sessions—extended lever increases mechanical advantage and reduces fatigue.

Durable, field-ready build

Constructed from high-strength aluminum alloy with a robust finish, the rounder resists corrosion, wear, and deformation. Its compact size and lightweight design suit professional technicians and serious DIYers alike for daily use.

Important notes

Not intended for Type K, L, or M copper tubes. Designed for ACR tubing sized by outer diameter (OD). Annealed tube sections are generally easier to work with by hand.
