Bosch GCG 18V-310 Cartridge caulking gun

The Bosch GCG 18V-310 cartridge caulking gun is a compact cordless tool for dispensing sealants and adhesives from cartridges up to 310 ml. Powered by the Professional 18V system, it offers a balance of portability and performance with a maximum push force of 3.5 kN and a feed rate up to 8 mm/s. The device includes an auto-reverse function that reduces pressure on the plunger rod when the trigger is released to prevent dripping and material overflow.

Advantages

The gun provides precise material control via nine selectable speed settings and a variable-speed trigger, enabling accurate application across a range of viscosities. Its cordless design is compatible with all Bosch Professional 18V batteries and chargers, simplifying use on-site. High push force and a steady feed rate support efficient work even with high-viscosity adhesives.

Suitable for

• Dispensing silicone, acrylic and polyurethane sealants
• Applying construction and assembly adhesives from standard 310 ml cartridges
• Sealing joints, gaps and penetrations in building and renovation work

After use, retract the plunger and remove any residual material from the nozzle.

Recommendations

For best results, choose a speed setting that matches the sealant viscosity and test on a scrap surface before working on the final joint. Store cartridges and the tool according to the manufacturer's guidance and clean the nozzle after each use to maintain consistent performance.
