Heavy-duty manual sealant gun designed around 400ml cartridge compatibility. Suited to routine sealing and adhesive work where a robust hand-operated tool is preferred.


Consistent Beads – Thanks to compatibility with 400ml cartridges

The mechanism accepts standard 400ml sealant cartridges, allowing the plunger to push sealant evenly along the cartridge nozzle. Manual trigger action controls the flow rate for steady extrusion.

Even bead lines reduce waste and speed up joint sealing, helping maintain neat finishes on windows, tiling and general repairs.

Durable Performance – With heavy-duty construction

The heavy-duty designation indicates reinforced components and a design intended for repeated use on tougher materials and frequent tasks. Components are chosen to withstand the pressure of thick sealants over time.

Robust build keeps the tool working reliably on renovation and site jobs, lowering the chance of early replacement.

Comfort for Longer Tasks – With an ergonomic trigger

Shaped trigger geometry spreads pressure across the hand during repeated squeezes, reducing concentrated strain on fingertips. Manual mechanical advantage aims to reduce the force needed per trigger pull.

Reduced hand fatigue makes long sealing runs more manageable and improves accuracy when working on long joints or multiple windows.
