Product Name
Leister 105.500 Wide Slot Nozzle 105.500 straight jaw 90° right angle bend, air outlet on both sides
Brief Description
This is a specialized wide slot nozzle accessory for Leister hot air welding tools, engineered for precision plastic welding applications. It features a 90° right-angle bend and air outlets on both sides, making it particularly effective for overlap welding in areas that are difficult to access.
Popular Applications & Uses
- Flat roof membrane welding- Pitched roof membrane welding- Pool waterproofing- Pond waterproofing- Tent tarpaulin welding- Advertising banner welding- Welding of inflatable plastic fabrics- Awning and wind blocker welding- Civil engineering/geomembrane welding- Welding of technical textiles and industrial fabrics- Repair work on truck tarpaulins and other technical textiles
Industries that Commonly Use It
- Construction/ Building Services (for roofing, waterproofing, civil engineering)- Plastic Fabrication (for general plastic welding, membranes, technical textiles)- Tarp, Fabric, Awning Manufacturing (for tarpaulins, banners, inflatable fabrics)- Sign & Display (for advertising banners)- Pool/Spa/Plumbing (for pool and pond waterproofing)- Fabrication (general fabrication involving plastic and textile welding)- General Manufacturing (for various manufacturing processes requiring hot air plastic welding)
Special and Unique Features
- 90° right-angle bend for accessing tight or challenging welding areas- Air outlet on both sides of the bent section, which is ideal for overlap welding as it applies heat parallel to the seam being welded- Precision engineered stainless steel construction for durability and heat resistance- Clamping connection for secure attachment to compatible hot air tools
Key Properties
- Material: Stainless steel- Nozzle connection diameter: 31.5 mm / 1.25 in- Slot length (a): 18 mm- Slot width (b): 3 mm- Angle (e): 15° (referring to the slot angle)- Bend (f): -120° (referring to the bend angle, though the product name specifies 90°)- Designed for use with Leister hot air blowers such as TRIAC AT, TRIAC ST, DIODE PID, and DIODE S
Surface Compatibility
- Various plastic membranes (e.g., for roofing, waterproofing)- Technical textiles (e.g., tarpaulins, banners, inflatable fabrics)- PVC, TPO, EPDM (common materials in roofing and waterproofing applications)
Known backups / known substitutes
- Leister 105.493 (discontinued predecessor with a 120° bend and single air outlet)- Other Leister wide slot nozzles with varying dimensions or angles, such as 107.123 (20x2mm, angled), 107.142 (20x2mm, 30° angled), 105.556 (20x2mm, 75° bend), 105.492 (20x2mm, 120° bent), 107.132 (40mm), 107.133 (40mm, perforated), 105.477 (20mm straight)
Comparison Note
The Leister 105.500 is an improved substitute for the discontinued Leister 105.493. The key difference is its 90-degree right-angle bend (compared to the 105.493's 120-degree bend) and the inclusion of air outlets on both sides of the bent section. This dual-sided air outlet design is specifically engineered to apply heat parallel to the seam, enhancing its performance for overlap welding tasks.
