The 10 gallon capacity of the CH-10al Cheetah Bead Seaters ASME certified tank will seat the bead on all truck and small tractor tires. A 2" tank opening allows use of the Magnum II barrel giving added "spread" of the discharge. This extends the power of the CH-10al for seating even the most difficult beads. Equipped with an Aluminum tank the larger tank is lighter than the Steel Tank.
