Huthbender Model 1685 Expander

Huth Expander Model 1685 Operations Manual

Huth redefines expanding portability and convenience with this down-sized, air-powered expanding unit. Ideal for making flares (requires part 440-flaring segment), ball joints (requires use of ball-joint segment tools), and slip connections under the vehicle or on the bench, Mitey Mate Jr. is not a lesser expander: it delivers both the power and the accuracy you demand.

Set to operate at 3200 psi (shop air pressure between 80 and 120 psi maximum - air regulator included in package) this pint-sized power-house puts 17,000 pounds of expanding force in your hands. Mitey Mate Jr. also comes with tooling to expand 1-1/2 to 2-1/2 inch I.D. mufflers and pipes (3, 3-1/2 or 4 inch capability with additional tooling).

It also comes with Huth's unique Accu-Sizer system for right-on expansions, job after job.

The expander itself, with its high-impact pistol grip, removable arbor tips and simple-to-setup bulls-eye sizing adjustments, weighs only 7 pounds. All three peices together weigh only 34 pounds.

The handy storage unit, which holds the expander, the three sement sets and one of the two detachable arbor tips, is 9 inch high by 10-1/2 inch square. The power pedal is only 8 inch high, 10 inch long, and 5 inch wide, and fits under the storage unit.
