Product Name
Leister 105.433 Narrow Preheat 0.2" - 5mm Round Speed Welding Nozzle
Brief Description
The Leister 105.433 is a precision-engineered stainless steel speed welding nozzle designed for hot air plastic welding. It features a narrow preheat and a 5mm round profile, making it ideal for high-speed, accurate welding of plastic materials, particularly in flooring applications. This push-fit nozzle is compatible with various Leister hot air tools.
Popular Applications & Uses
- High-speed precision plastic welding and repair- Welding of vinyl and linoleum flooring- Sealing geomembranes and other plastic components in construction- Repairing plastic components such as car bumpers and kayaks- Welding thermoplastic materials, including HDPE, PP, PVC-U, PVC-C, PA, PVDF, and ECTFE- Heat sealing of single-ply flexible plastics, lining membranes, coated materials, films, foams, and sheets
Industries that Commonly Use It
- Flooring Installer or Manufacturer- Plastic Fabrication- Construction/ Building Services- Automotive Service/Repair- Marine- General Manufacturing- Tarp, Fabric, Awning Manufacturing
Special and Unique Features
- Narrow preheat design for precise heat application- Small air-slide mechanism- Push-fit connection for easy attachment to compatible hot air tools- Made from precision-engineered stainless steel for durability- Two-pronged design allows welding rod to glide smoothly while hot air passes through the main nozzle, preventing scorching
Key Properties
- Material: Precision-engineered stainless steel- Nozzle Connection Ø: 8 mm / 0.3 in- Suitable Welding Rod: Profile D ø5 (5mm round welding rods)- Compatibility: Designed for use with Leister TRIAC (all models), HOT JET S, DIODE S, and LABOR S hot air tools, often requiring a tubular nozzle- Air Slot: Narrow air slot
Surface Compatibility
This nozzle is primarily used for welding various thermoplastic materials, including:- Polyurethane (PU) protected floors- Polyvinyl Chloride (PVC) protected floors (vinyl and linoleum)- High-Density Polyethylene (HDPE)- Polypropylene (PP)- PVC-U, PVC-C, PA, PVDF, and ECTFE- Coated fabrics, foils, foams, tiles, and sheets
Known backups / known substitutes
- Leister 3mm Round Speed Weld Nozzle (e.g., 105.431, 106.989)- Leister 4mm Round Speed Weld Nozzle (e.g., 105.432, 106.990)- Leister Triangular Speed Welding Nozzles (e.g., 5.7mm 106.992, 7mm 106.993)- Leister Wide Slot Nozzles (various sizes and angles) for different welding tasks- Other Leister speed welding nozzles with different profiles (e.g., Profile A, B, C)
Comparison Note
The Leister 105.433 Narrow Preheat 0.2" - 5mm Round Speed Welding Nozzle is specifically designed for applications requiring a narrow preheat and a 5mm round welding rod, making it highly specialized for tasks like flooring installation and detailed plastic fabrication. While other Leister nozzles offer different profiles (e.g., triangular, wide slot) or diameters (e.g., 3mm, 4mm) for varied welding needs, this particular nozzle excels in precision round speed welding, especially for vinyl and linoleum floors. Its narrow preheat and small air-slide are key differentiators for controlled heat application.
