Systems and methods for dispensing a viscous fluid using an apparatus that may include: a housing; an applicator coupling on the housing that can releasably couple an applicator that contains a viscous fluid; a gas supply coupling that receives a pressurized gas from a gas supply; a valve having a first open position in which the valve can be gradually and controllably opened to adjustably control the delivery of pressurized gas to the applicator coupling, and a second closed position where the pressurized gas delivered to the applicator coupling is vented; and a valve actuator configured to permit a user to gradually and controllably open the valve to controllably dispense the viscous fluid from the applicator, where ceasing to depress the valve actuator vents the applicator coupling and immediately discontinues the dispensing of viscous fluid from the applicator.

A sealant dispenser comprising: a hollow can which includes an accommodation chamber, an opening, a connection seat, chemical sealant, an insertion, and the two peripheral ribs formed on a bottom of the insertion. A sealant dispenser is fixed on an accommodation box in which an air compressor is accommodated, the accommodation box includes a fixing hole, a U-shaped protrusion formed on a lower end of the fixing hole, a positioning space defined on the fixing hole above the U-shaped protrusion, and a peripheral column surrounding around the fixing hole, the U-shaped protrusion and the positioning space. The insertion of the hollow can is inserted into the fixing hole of the accommodation box, and the sealant dispenser is rotated so that the two peripheral ribs of the insertion are retained with the positioning space of the fixing hole, thus fixing the sealant dispenser on the accommodation box.

A method of applying a viscous material to a fastener comprises aligning a nozzle relative to the fastener by engaging an aligner with the fastener. Engaging the aligner with the fastener comprises positioning the aligner over the fastener and advancing a biasing tube toward the fastener to establish contact between the aligner and a structure to partially retract the aligner into the biasing tube until a plurality of surfaces of the aligner contacts one or more outer surfaces of the fastener. A flexible wall of a dispenser bellows is deflected by expanding a pressure-application device, which is configured to apply pressure on the flexible wall of the dispenser bellows, wherein the dispenser bellows is in fluid communication with the nozzle. The viscous material is expelled from the dispenser bellows responsive to deforming the flexible wall.
