Dispensing Squeeze Gun FISCHER 53115 — hermetic design for sealants and adhesives

FISCHER Squeeze Gun 53115 is a dispensing tool with a hermetic design for controlled application of sealants and adhesives. The hermetic mechanism reduces leakage from cartridges and ensures a steady bead flow, enabling precise application along joints and seams. The tool is compatible with standard cartridge-based sealants and adhesives, intended to improve dispensing accuracy, reduce material waste and ease manual handling during sealing, bonding and filling tasks.

Advantages

The hermetic design minimizes backflow and prevents product drying inside the cartridge tip, which helps maintain consistent dispensing performance. The squeeze gun provides controlled pressure transmission from the trigger to the cartridge, improving bead uniformity and reducing hand fatigue during repetitive use. Its construction supports easy mounting and removal of cartridges and simplifies cleaning compared with open-frame applicators.

Suitable for

• Applying silicone, acrylic and polymer-based sealants for joints and seams
• Dispensing construction and industrial adhesives for bonding tasks
• Controlled filling of gaps and cracks in renovation and DIY projects
• On-site sealing work where reduced leakage and precise bead control are required

Key specifications

• Hermetic dispensing mechanism to reduce leakage and clogging
• Compatible with standard cartridge-based sealants and adhesives
• Manual squeeze/trigger operation for controlled bead application
• Design focused on steady pressure transmission and uniform flow

How to use

Insert the appropriate cartridge into the FISCHER Squeeze Gun 53115 following the cartridge orientation indicated on the tool. Cut the cartridge nozzle to the required bead diameter and attach the nozzle. Squeeze the trigger evenly to start dispensing; adjust pressure and trigger cadence to control bead size and flow. After use, release residual pressure according to the tool’s procedure and remove the cartridge if necessary. Clean the nozzle and external surfaces of the gun to prevent material buildup and ensure long-term performance.

Recommendations

Use cartridges and sealants recommended for cartridge dispensing; pre-test bead size and adhesion on a scrap surface before application. Store the tool and cartridges in a dry environment and avoid prolonged exposure of uncapped cartridges to air. Follow safety and handling instructions of the sealant or adhesive manufacturer, including ventilation and personal protective equipment where required.
