An Economical, Durable Tool

Elliott’s 40 Series Straight Boiler Expanders are recommended for re-rolling leaky tube joints in Firetube boilers. Self-feeding, these expanders can be used by hand or powered by a rolling motor for fast tube rolling.

Guard Prong Accommodates Tube Projections

The guard prong is ½” (12.7mm) long, allowing you to roll boiler tubes with a projection, while also controlling the mandrel feed to prevent over-rolling.

Torque Controlled Tube Rolling

The bronze bearing between the expander’s frame and guard reduces friction and allows for torque controlled tube rolling.

Only for re-rolling leaky tube joints in firetube boilers.

Tapered expansion aggressively seals leaky joints allowing for quick cycle time.

An economical, durable tool.
