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"
