Product Name
Leister 105.493 Wide Slot Nozzle, Straight Jaw 120° Bent at Right Angle (Discontinued)
Brief Description
This product was a discontinued wide slot nozzle accessory for Leister hot air welding tools, specifically designed with a 120° right-angle bend for specialized plastic welding applications. It was compatible with Leister hot air guns such as the Triac ST, Triac AT, and Diode PID/S.
Popular Applications & Uses
- Hot air plastic welding of various thermoplastic materials.- Welding of single-ply roofing membranes, including TPO, PVC, and EPDM.- Sealing geomembranes in civil engineering projects such as landfills, tunnels, and reservoirs.- Welding technical textiles and industrial fabrics.- Joining and shaping plastic components like tanks, pipes, tubing, and connectors.- Floor welding, particularly for vinyl and linoleum surfaces.
Industries that Commonly Use It
- Construction/Building Services (for roofing, flooring, and civil engineering applications)- Plastic Fabrication (for general plastic welding and component manufacturing)- Flooring Installer or Manufacturer (specifically for floor welding tasks)- Tarp, Fabric, Awning Manufacturing (for welding technical textiles and tarpaulins)- General Manufacturing (for diverse manufacturing processes involving plastic welding)
Special and Unique Features
- 120° bent at right angle: This specific angle allowed for improved access to difficult-to-reach areas or facilitated particular welding techniques.- Wide slot design: Provided a broad and even distribution of hot air, crucial for efficient and consistent welding.- Designed for use with professional Leister hot air hand tools.
Key Properties
- Material: Typically constructed from precision engineered stainless steel, ensuring durability and heat resistance (based on similar Leister nozzles).- Angle: Features a 120° bend at a right angle.- Connection: Utilized a clamping connection for secure attachment to the hot air tool (for similar nozzles).- Compatibility: Engineered for use with Leister hot air tools such as the Triac ST, Triac AT, and Diode PID/S.
Surface Compatibility
- Various thermoplastics, including PVC, TPO, EPDM, PP, and PE.- Single-ply roofing membranes.- Geomembranes used in civil engineering.- Technical textiles and industrial fabrics.- Vinyl and linoleum flooring materials.
Known backups / known substitutes
- Leister 105.500: This is identified as a direct substitute, offering the same basic style but with a 90-degree bend instead of 120°.- Other Leister wide slot nozzles: Various straight or angled wide slot nozzles are available in different widths (e.g., 20mm, 40mm, 80mm) for general plastic welding applications.- Compatible wide slot nozzles from other manufacturers: Brands like BAK, HERZ, Forsthoff, or SIEVERT produce wide slot nozzles that can be used with Leister Triac-compatible hot air hand welders.
Comparison Note
The Leister 105.493 was distinguished by its specific 120° right-angle bend, which provided a unique advantage for accessing confined spaces or executing particular welding seams. While substitutes like the Leister 105.500 offer a similar bent design (90°), the exact 120° angle of the 105.493 might require users to adapt their technique or tool positioning when using alternative nozzles. Straight wide slot nozzles would offer broader application but lack the specialized access provided by a bent design.
