Esco MILLHOG® Rolling Motors and Tube Expanders are air-powered and feature a torque control setting which stalls the tool when it reaches the desired tube expansion to prevent over-under expansion. Enabling users to create a uniform and tight mechanical seal, these tube sheet expanders are easy to adjust and allow precise torque control from 25 to 325 ft.-lbs.

Available with 90, 190, and 280 RPM motors, the right angle style Esco MILLHOG® Rolling Motors and Tube Expanders are offered as kits for tubes from 3/8” to 4-1/2” O.D. and tube sheets to 5-3/8”. Supplied complete and ready to use with standard shop air, they are ideally suited for creating mechanical seals in boilers, heat exchangers, and condensers.
