TUBE EXPANDER EQUIPMENT AND TOOLS

WILSON LINSEN EXPANDER

Linsen Flaring Expander — 3/8 to 1-Inch Outer Diameter
Flaring Expander

The Linsen Expanders are power-driven tools designed for making tubing connections without fittings. It enlarges the end of a tube, leaving .015-inch clearance for slip fit, so that another tube can be inserted and soldered like a sweat fitting. It is excellent for short bends, U-turns, copper, brass, aluminum, or thin steel tubing.
