Product Name
Leister 106.992 5/32" - 4mm Triangle Speed Welding Nozzle
Brief Description
This is a precision-engineered stainless steel triangular speed welding nozzle, specifically designed for use with Leister hot air welding tools like the TRIAC, DIODE, HOT JET S, and LABOR S. It facilitates rapid and efficient welding of thermoplastic materials using triangular welding rods.
Popular Applications & Uses
- Speed welding of plastic sheets and membranes- Welding of PVC and vinyl flooring- Roofing membrane installation and repair- Plastic tank fabrication and repair- Boat construction and repair- Welding of flexible tanks, pipes, and tubes- General plastic fabrication and repair tasks where time efficiency is crucial
Industries that Commonly Use It
- Plastic Fabrication- Construction/ Building Services- Flooring Installer or Manufacturer- Tarp, Fabric, Awning Manufacturing- Marine- General Manufacturing
Special and Unique Features
- **Speed Welding Design:** Allows for continuous, more efficient welding by combining hot air application and welding rod feeding in a single motion.- **Triangular Profile:** Specifically designed to accept 5.7mm Profile A triangular welding rods, ensuring a precise fit and strong weld.- **Precision Engineered:** Made from high-quality stainless steel for durability and consistent performance.- **Direct Airflow:** Features a 2-pronged design that directs hot air directly onto the seam, preventing scorching of material edges.- **Leister Compatibility:** Designed to push-fit onto 5mm tubular nozzles of various Leister hot air guns (TRIAC, DIODE, HOT JET S, LABOR S).
Key Properties
- **Material:** Precision engineered stainless steel. Some similar nozzles can be titanium alloy for enhanced durability and heat resistance.- **Size:** 5/32" - 4mm (or 5.7mm Profile A) for the welding rod profile.- **Nozzle Connection:** Push-fit connection, typically onto an 8mm / 0.3 inch nozzle connection, requiring a 5mm round tubular nozzle as a base.- **Heat Resistance:** Designed to withstand high temperatures generated by hot air welding tools.- **Durability:** Robust construction for prolonged use in demanding environments.
Surface Compatibility
- Polypropylene (PP)- Polyethylene (PE)- Polyvinyl Chloride (PVC)- Polycarbonate- Thermoplastic membranes and sheets- Vinyl and linoleum flooring
Known backups / known substitutes
- Other Leister speed welding nozzles with different profiles (e.g., round speed nozzles, tape speed nozzles).- Standard tacking nozzles for initial joint alignment.- Wide slot nozzles for broader applications or surface heating.- Extrusion welders for heavier gauge plastic welding applications.- Nozzles from other compatible hot air tool manufacturers (though Leister nozzles are often specific to their tools).
Comparison Note
The Leister 106.992 triangular speed welding nozzle is highly efficient for long weld runs on materials compatible with triangular welding rods, offering significant time savings over manual welding or using standard tacking nozzles. Its specialized design ensures consistent heat application and rod guidance. However, it requires the use of specific triangular welding rod profiles and a compatible 5mm tubular nozzle, making it less versatile for applications requiring different rod shapes or very fine detail work compared to a general-purpose nozzle.
