The Ken-Tool Mega AirBlast Bead Seater, No. 31444, is designed to properly and efficiently seat the bead of tubeless tires to the rim. The tool uses pressurized air to uniformly force the tire's bead onto the rim before inflating the tire to the correct pressure. It has an operating maximum pressure of 120 psi. A portable, steel 5-gal air reservoir tank is the center of the No. 31444. The tank is ASME and CE certified. A heavy duty, 2" diameter tube with a ball valve carries the air to the insertion point between the bead and the rim. Plastic nose clip protects chrome and alloy wheels (replacements available). The bead seater is nitrogen compatible and features a digital gauge with backlight capability.
