## Long description

The Högert Technik HT4R422 polyurethane foam gun is a professional-grade tool engineered for the precise and efficient application of mounting foam. Designed for construction and renovation professionals, this applicator features a robust construction that withstands the rigors of daily site use. The integrated needle is coated with PTFE, a specialized material that significantly reduces foam adhesion, ensuring consistent flow and simplifying the cleaning process after use.
Advantages
The primary benefit of this foam gun is its high-precision flow control, which allows users to apply foam exactly where needed without excessive waste. The PTFE-coated needle is a critical feature that prevents the foam from hardening inside the mechanism, thereby extending the tool's lifespan and maintaining smooth operation over time. Its ergonomic design ensures comfortable handling during extended periods of work, while the durable build quality provides reliable performance in various environmental conditions.
Suitable for
Sealing gaps around window and door frames
Insulating wall cavities and pipe penetrations
Filling voids and cracks in masonry or concrete
General construction and renovation sealing tasks
When it may not be suitable
This tool is specifically designed for standard polyurethane mounting foam canisters. It may not be compatible with specialized industrial adhesives or non-standard foam containers that require unique proprietary applicators.
Key specifications
Material: Durable metal construction
Needle coating: PTFE for non-stick performance
Application: Precision foam control
Compatibility: Standard polyurethane foam canisters
How to use
To use the Högert Technik foam gun, first ensure the foam canister is shaken thoroughly according to the manufacturer's instructions. Remove the protective cap from the canister and screw it securely onto the gun's adapter. Once attached, adjust the flow control knob at the rear of the tool to set the desired foam output. Point the nozzle into the gap or cavity and pull the trigger to apply the foam. After finishing the task, it is recommended to clean the nozzle and the internal mechanism using a dedicated foam cleaner to prevent residue buildup.
What to consider before purchase
Ensure your foam canisters are compatible with standard threaded foam gun adapters
Consider the frequency of use to determine if a professional-grade tool is required
Verify that you have appropriate foam cleaner solvent on hand for maintenance
Usage recommendations
Always wear protective gloves and safety glasses when working with polyurethane foam. Ensure the workspace is well-ventilated during application and store the tool in a dry place when not in use to maintain the integrity of the PTFE coating.
