Linsen Expander – 3/8” to 1” Outer Diameter
Linsen Expanders are power-driven tools designed for making tube connections without fittings. This expander enlarges the end of a tube leaving a .015-inch clearance for slip that allows for another tube to be inserted and soldered. This type of expander is perfect for short bends, U-turns, copper, brass, aluminum or thin steel tubing.
