Product Name
Leister 142.281 Wide slot nozzle with scraper (ø 50.0) 74 x 3 mm
Brief Description
This is a specialized accessory for Leister hot air tools, designed for precision hot air application with an integrated scraper. It facilitates tasks requiring both heat and mechanical action, such as plastic welding, heat sealing, and surface preparation.
Popular Applications & Uses
- Plastic welding and fabrication- Heat sealing of various flexible plastics, lining membranes, coated materials, films, foams, and sheets- Roofing membrane welding- Flooring materials welding, including vinyl and linoleum- Civil engineering applications, such as sealing geomembranes in landfill projects and tunnels- Shrinking applications for tubes and electrical interconnection devices- Drying paint and varnish- Activating hot melt adhesives- Car repairs, including fixing bumpers- Joining billboards and flex banners- Color removal- Surface preparation, cleaning, and deburring due to the integrated scraper
Industries that Commonly Use It
- Construction/ Building Services (for roofing, flooring, civil engineering, waterproofing)- Plastic Fabrication (for welding and forming plastic components)- Flooring Installer or Manufacturer (for vinyl and other flooring installations)- Tarp, Fabric, Awning Manufacturing (for heat sealing various flexible materials)- General Manufacturing (for diverse heat-related production processes)- Automotive Service/Repair (for plastic repairs)- Sign & Display (for joining large format flexible media)- Cladding (for sealing and joining exterior building materials)
Special and Unique Features
- Integrated scraper for simultaneous heat application and material removal/surface preparation- Wide slot design for efficient and broad heat distribution- Clamping connection for secure attachment to compatible Leister hot air tools- Precision engineered for consistent performance with Leister hot air guns
Key Properties
- Material: Made of hardened steel, often 304 stainless steel- Temperature Tolerance: Up to 800°C- Nozzle Connection Diameter: 50 mm / 2 inches- Slot Length: 74 mm / 2.91 inches- Slot Width: 3 mm / 0.11 inches- Compatibility: Designed for use with Leister hot air tools like TRIAC ST, TRIAC AT, and ELECTRON ST
Surface Compatibility
- PVC (Polyvinyl Chloride)- PP (Polypropylene)- ABS (Acrylonitrile Butadiene Styrene)- HDPE (High-Density Polyethylene)- Vinyl and Linoleum flooring materials- Single-ply flexible plastics, lining membranes, coated materials, films, foams, and sheets- Bitumen (other wide slot nozzles are specified for bitumen, implying general compatibility for heat-sensitive materials)
Known backups / known substitutes
- Other Leister wide slot nozzles with different dimensions or angles (e.g., 107.653 (75x2mm), 107.130 (40x2mm angled), 105.992 (400x4mm))- Leister standard tubular nozzles or speed welding nozzles for specific welding tasks without the scraper feature- Nozzles from other hot air tool manufacturers, though Leister accessories are often optimized for their tools
Comparison Note
This specific Leister wide slot nozzle stands out due to its integrated scraper, offering a dual function of heat application and mechanical surface action. This makes it particularly efficient for tasks requiring simultaneous material preparation or removal alongside hot air welding or sealing, differentiating it from standard wide slot nozzles that only provide heat. Its robust construction and precise dimensions ensure optimal performance and compatibility with Leister's professional-grade hot air tools.
