Caulking Gun Tajima Convoy Lite – manual cartridge gun for sealants and adhesives, model CNV-LITE

The Tajima Convoy Lite caulking gun (CNV-LITE) is a manual cartridge applicator designed to dispense sealants and adhesives from standard cartridges with steady control. Intended for general sealing, filling and bonding tasks, this gun offers a compact, lightweight design that facilitates one-handed operation in construction, renovation and DIY projects. It is compatible with common caulking materials and provides consistent bead application for window and door sealing, joint repairs and general maintenance.

Advantages

The Convoy Lite features an ergonomic handle and a smooth drive mechanism that reduce hand fatigue during repetitive use. Its lightweight construction improves maneuverability in confined or overhead spaces while maintaining reliable dispensing force for typical sealants and adhesives. The simple cartridge insertion and release mechanism ensures quick material changes and easy cleaning after use.

Suitable for

• Applying silicone, acrylic or hybrid sealants around windows and doors
• Sealing joints and gaps in interior and exterior finishes
• Dispensing adhesives for light bonding tasks in renovation work
• General maintenance and repair where controlled bead application is required

Key specifications

• Operation: manual, finger-trigger actuation for controlled dispensing
• Cartridge compatibility: standard sealant/adhesive cartridges (common industry sizes)
• Construction: lightweight body designed for reduced user fatigue
• Ergonomics: contoured handle for improved grip and control
• Mechanism: smooth drive for consistent bead output

How to use

Load a standard cartridge into the gun by pulling back the plunger, inserting the cartridge, and engaging the drive. Cut the cartridge nozzle to the required bead size and pierce the inner seal if present. Hold the gun at a consistent angle and squeeze the trigger smoothly to lay an even bead of sealant or adhesive along the joint. Release pressure and use the cartridge release lever when finished to stop material flow and remove the cartridge for replacement or storage.

Usage recommendations

For best results, use with cartridges within the supported size range and choose a nozzle opening matched to the joint width. Clean the gun after use to prevent cured material buildup, and store it in a dry place. For thicker or high-viscosity materials, apply steady, even pressure to maintain a consistent bead.
