A full line of air-powered tube expanders and rolling motors for creating steel-to-steel mechanical seals in boilers, heat exchangers, and condensers is available for sale or rent from ESCO Tool of Holliston, Massachusetts.

ESCO MILLHOG® Tube Expanders and Rolling Motors are air-powered and feature precise torque control from 25 to 325 ft.-lbs. for tube expansion and wall reduction to create tight tube joints. Once the proper torque level is established, this setting can be retained so that each time the throttle is engaged the tool will stall when it reaches the desired tube expansion.

Allowing operators to rapidly roll multiple tubes, ESCO MILLHOG® Tube Expanders and Rolling Motors are offered in five kits to accommodate tubes from 1” I.D. to 4-1/4” O.D. and 1 to 20 Ga wall thickness and include a 6 ft. hose whip and all required tools. Configurations include straight and right angle rolling motors for straight and flare rolls.

ESCO MILLHOG® Tube Expander Kits are available for rent at $380.00 per week in the continental U.S.A. and can be purchased for $3,995.00 up.
