Product Name
Leister 107.135 Wide Slot Nozzle 1.6 Inch with PTFE Teflon Plastic Coated
Brief Description
This is a specialized wide slot nozzle accessory for Leister hot-air welding tools, designed for precision plastic welding and processing. It features a 1.6-inch (40mm) slot and is coated with PTFE (Teflon) to provide non-stick properties, making it ideal for working with various thermoplastic materials and membranes.
Popular Applications & Uses
- Welding of single-ply roofing membranes.- Repair and installation of truck tarpaulins, tents, awnings, and advertising banners.- Waterproofing applications in construction, such as flat roofs, foundations, ponds, tunnels, and landfills (geomembranes).- General plastic fabrication and repair, including shaping and molding thermoplastics.- Floor laying, particularly for vinyl floor coverings.- Welding of technical textiles and industrial fabrics.- Bitumen welding applications.
Industries that Commonly Use It
- Construction/ Building Services- Plastic Fabrication- Tarp, Fabric, Awning Manufacturing- Flooring Installer or Manufacturer- Sign & Display- General Manufacturing- Automotive Service/Repair- Marine (Aquaculture, Boat construction/repair)- PVC Trimboard- Cladding
Special and Unique Features
- **PTFE (Teflon) Coating:** Provides excellent non-stick/release properties, preventing molten plastic from adhering to the nozzle, ensuring cleaner welds and easier cleaning.- **Wide Slot Design (1.6 inch / 40mm):** Ideal for applying hot air over larger surface areas, facilitating efficient welding of membranes and sheets.- **Durable Construction:** Made from 304 stainless steel for high heat resistance and longevity.- **Compatibility:** Designed for use with popular Leister hot-air tools such as the TRIAC ST, TRIAC AT, DIODE PID, and DIODE S.- **Clamping Connection:** Ensures a secure fit to the hot air tool.- **Angled Design (15°):** Some versions of wide slot nozzles have an angle, which can be beneficial for accessing tight edges and specific welding tasks.
Key Properties
- **Material:** 304 Stainless Steel with PTFE coating.- **Nozzle Connection Diameter:** 31.5 mm / 1.25 inches.- **Slot Length:** 40 mm / 1.57 inches.- **Slot Width:** 2 mm / 0.07 inches.- **Max. Peak Temperature:** Stable up to 260 °C (500 °F) for the PTFE coating.- **Non-stick Surface:** Facilitates easy release of melted plastic.- **Corrosion and Chemical Resistance:** PTFE enhances resistance to chemicals.
Surface Compatibility
- Thermoplastics (e.g., PVC, Polypropylene, Polyethylene).- Single-ply roofing membranes.- Geomembranes (for landfill and tunnel engineering).- Technical textiles and industrial fabrics (e.g., tarpaulins, banners, awnings).- Bitumen.- Vinyl floor coverings.
Known backups / known substitutes
- Other Leister wide slot nozzles of different sizes or angles (e.g., 20mm, 60mm, 80mm, straight, angled).- Wide slot nozzles from compatible brands like BAK or Steinel, designed for similar hot-air tools.- Uncoated stainless steel wide slot nozzles (though these would lack the non-stick benefit).- Other types of plastic welding nozzles (e.g., speed welding nozzles, tacking nozzles) for different applications.
Comparison Note
The Leister 107.135 stands out due to its PTFE Teflon coating, which significantly improves the welding process by preventing material adhesion, reducing cleaning time, and extending nozzle lifespan compared to uncoated alternatives. Its specific 1.6-inch (40mm) wide slot and 15° angle (as per some sources) make it particularly effective for broad, flat welds and accessing certain areas, offering a balance between coverage and maneuverability.
