Wilson’s Series 22 Expander Tools were specially designed for use in boiler rooms, boiler repair shops, railroads, Scotch Marine Boilers, as well as, for all general rolling in fire tube boilers where flaring is not required. The over-sized Series 22 model is offered for use in opening up existing tube holes. A revolving thrust collar helps eliminate jamming and its compact designs allows for working close to walls or adjacent tubes.
