Rolling motors and tube expanders are air powered. They have a torque-control setting that stalls the tool when it reaches the desired tube expansion to create a uniform and tight mechanical seal. Features include a selection of adapters and universal pivoting extensions that let users reach around obstructions and roll hard-to-access exchanger tubes. Supplied as complete kits for straight-, flare-, long-reach and beaded rolls, the rolling motors and tube expanders are available with 90-, 190- and 280-rpm motors that operate on standard shop air.
