Product Name
Leister 106.990 4mm Round Speed Welding Nozzle
Brief Description
This is a precision-engineered stainless steel accessory for Leister hot air welding tools, designed to facilitate rapid and continuous plastic welding. It works by simultaneously applying hot air and guiding a 4mm round welding rod into the weld area, significantly increasing efficiency compared to traditional pendulum welding.
Popular Applications & Uses
- High-speed precision plastic welding- Joining thermoplastic materials- Fabrication and repair tasks- Welding of vinyl and linoleum flooring- Roofing applications- Plastic tank and container construction- Automotive bumper repair and vehicle repairs- Boat construction and repair- Geomembrane sealing in landfill projects, tunnel construction, and hydraulic engineering- Manufacturing of plastic components for industrial systems- Processing of tarpaulins and plastic sealing sheets
Industries that Commonly Use It
- Plastic Fabrication- Construction/ Building Services (including roofing, civil engineering, tunnel construction, landfill projects)- Flooring Installer or Manufacturer- Automotive Service/Repair- Marine (for boat and aquaculture construction/repair)- General Manufacturing (for plastic components and tanks)- Tarp, Fabric, Awning Manufacturing
Special and Unique Features
- Facilitates rapid and continuous welding by combining hot air application and welding rod feeding in one motion- Precision engineered for strong, consistent welds in thermoplastic materials- Push-fit connection for easy attachment to compatible 5mm tubular nozzles- Two-pronged design allows the welding rod to glide smoothly while hot air passes through the main nozzle, preventing scorching- Designed to accept 4mm round welding rods- Made from durable stainless steel
Key Properties
- Material: Precision engineered stainless steel (304 stainless steel mentioned for a similar product)- Nozzle connection: Push-fit onto 5mm tubular nozzles- Welding rod compatibility: 4mm round welding rods- Compatibility: Designed for use with Leister hot air guns such as TRIAC ST, TRIAC AT, DIODE PID/S, HOT JET S, and LABOR S models- Function: Directs and controls the flow of heated air for precise heat application
Surface Compatibility
- Thermoplastic materials including PP (polypropylene), PE (polyethylene), HDPE, MDPE, LDPE, PVC (polyvinyl chloride), ABS, and polycarbonate- Vinyl and linoleum flooring
Known backups / known substitutes
- Other types of plastic welding nozzles, such as tubular nozzles (pencil tips), bended nozzles, overlap nozzles, tacking nozzles, flare nozzles, reduction nozzles, reflector nozzles, slit nozzles, threaded nozzles, wide slot nozzles, and window nozzles- Different sizes of round speed welding nozzles (e.g., 3mm, 5mm)- Triangular speed welding nozzles (e.g., 5.7mm, 7mm)- Fillet weld speed nozzles- Manual "pendulum welding" technique (slower than speed welding)- Nozzles from other manufacturers compatible with Leister tools or other hot air welding tools (e.g., BAK RiOn, Forsthoff, Miller Weldmaster, Steinel)
Comparison Note
The Leister 106.990 4mm Round Speed Welding Nozzle offers a significantly faster and more efficient welding process compared to the traditional "pendulum welding" technique, especially for long weld runs, by integrating the hot air application and welding rod feeding. Its precision-engineered design ensures consistent and strong welds, making it a preferred choice for professionals seeking high-quality and time-saving solutions in plastic fabrication and repair. It requires a compatible 5mm tubular nozzle for attachment to the hot air welding tool.
