UNi-PRO Genius Heavy Duty No-Drip Caulking Gun

The UNi-PRO Genius is a heavy duty no-drip caulking gun for cartridges and sealant tubes. The stop flow trigger release stops the flow the moment you let go, so there is no mess or wasted sealant. A positive compound advance keeps the pressure steady, and the rotating barrel gives you easy access to corners. The low fatigue trigger and handle make long runs of sealing more comfortable. It suits roof and gutter sealing, window and door caulking, and any job that needs a clean, controlled bead of sealant or adhesive.

Frequently Asked Questions

What does no-drip mean?

A no-drip gun uses a stop flow trigger that pulls the plunger back slightly when you release it. That relieves the pressure and stops the sealant flowing, so you do not get a messy drip after every squeeze. It saves sealant and leaves a cleaner job, which matters on long sealing runs.

Why does the barrel rotate?

The rotating barrel lets you turn the gun to reach corners and awkward angles without twisting your wrist or moving the cartridge. That is handy when you are sealing around flashings, eaves, windows and trim where the gun needs to sit at an angle to the joint.

What cartridges fit this gun?

The gun is built for standard 300ml and similar sealant and adhesive cartridges used in building work. The positive compound advance and stop flow trigger work with the common cartridge formats sold in the store, including roof and gutter sealants and high tack adhesives.

How do I use the built-in nozzle cleaner?

The gun has a nozzle cleaner built in, so you can clear a blocked or sealed nozzle without carrying a separate tool. Remove the cartridge, use the cleaner to clear the nozzle opening, and fit the cartridge back on for the next run. Keeping the nozzle clear gives a cleaner bead.
