The 850ml Jumbo Cartridge Gun is a manual dispensing tool for compatible large-format sealant and adhesive cartridges. Its steel frame and geared mechanism are designed to help dispense thicker materials during construction and joint sealing work.
This gun is intended for 850ml cartridge formats, not standard 310ml cartridges or 600ml foil sausages. Check cartridge dimensions and compatibility before ordering.
Low gearing pushes thick structural sealants without stalling.
Steady bead pressure fills joints without voids.
360-degree rotating frame keeps the nozzle square in tight joints.
Load the 850ml cartridge, cut and purge, and bead with slow, even trigger strokes. Low gearing is deliberate: let it push rather than racing the trigger. Clean the drive plate and plunger after use.
Takes 850ml jumbo cartridges only; standard 300ml cartridges will not seat. Slow by design, so not the gun for fast thin beads.
