Sealant gun Polax 26-003 for 300 ml cartridges

Polax 26-003 manual sealant gun is designed for use with standard 300 ml cartridges to dispense sealants, adhesives and caulks. The tool provides steady, controlled extrusion and precise bead placement for sealing joints, filling gaps and applying adhesives during construction, glazing, sanitary installations and general repair tasks. Its manual operation makes it suitable for intermittent use on-site and for DIY projects where portability and direct control over flow rate are important.

Advantages

The Polax 26-003 sealant gun delivers consistent material flow and accurate bead control, reducing waste and mess during application. Its ergonomically shaped handle and trigger mechanism are engineered to minimize user fatigue and allow steady pressure for smooth dispensing. The robust frame and cartridge support ensure reliable alignment of the tube, while the simple release mechanism enables quick cartridge changes and controlled retraction of the push rod.

Suitable for

• Applying silicone, acrylic or polyurethane sealants in sanitary and glazing work
• Dispensing adhesives and construction sealants for interior finishing
• Home repairs and DIY projects requiring precise bead lines
• Sealing joints around windows, doors and fixtures

Key specifications

• Compatibility: standard 300 ml cartridge size
• Operation: manual trigger mechanism for controlled extrusion
• Frame: durable support frame for cartridge stability
• Handle: ergonomic design to reduce hand fatigue
• Release: quick-release or retraction mechanism for push rod control

How to use

Insert a compatible 300 ml cartridge into the frame, cut the cartridge nozzle to the desired bead size and puncture the inner seal if required. Squeeze the trigger gently to begin dispensing, adjusting pressure to control the flow and bead width. Use steady, continuous motion along the joint for an even bead. When stopping, engage the release mechanism to reduce residual pressure and prevent excess leakage. Remove and replace the cartridge as needed following safe disposal guidelines for the used material.

Usage recommendations

For best results, select a nozzle opening appropriate to the joint width and practice on scrap material to set trigger pressure. Maintain the tool by keeping the push rod and frame clean after use, avoid prolonged exposure to corrosive materials, and store the sealant gun in a dry environment. Wear appropriate personal protective equipment such as gloves and eye protection when handling sealants and adhesives.
