tube expanders for condensers, heat exchangers, boilers, air heaters and oil coolers

AL series tube expanders

The AL Series is an expander which is used to enlarge the ends of soft tube so that  another tube of the same size can be inserted into the expanded section and soldered for a leak proof joint. The tube expanders are designed to leave a 0.015" clearance for a slip connection and soldering. Special sizes and shanks are available on request. Average depth of expansion is 3/4"

Consult the PDF Specifications below to cross refer all data to the tube OD, wall thickness and tube sheet thickness. Also, part numbers for spare mandrels and rollers can be found here. If the PDF is two pages then the data has to be read across the two pages.
