WK-650 Tube Expander

The WK-650 Tube Expander is a professional hand tool engineered for accurate expansion of large-diameter copper tubing in HVAC and refrigeration applications. It allows technicians to expand tube ends for direct tube-to-tube connections without the need for additional fittings, reducing joints and potential leak points.

Built for smooth and controlled operation, the WK-650 ensures uniform expansion while protecting the tubing wall from deformation. Its robust construction provides reliable performance during installation, maintenance, and repair work. With a working range from 1/4″ to 2″ (6–50 mm), it is suitable for a wide variety of copper tubing used in commercial and industrial refrigeration and air conditioning systems.
