Product Name
Leister 156.470 Speed welding nozzle 5mm bent
Brief Description
This is a specialized 5mm bent speed welding nozzle from Leister, designed as an accessory for hot air plastic welding tools. It facilitates high-speed, precise welding of thermoplastic materials using a welding rod.
Popular Applications & Uses
- Welding polyurethane and PVC protected floors (vinyl and linoleum).- High-speed precision plastic welding in fabrication and repair.- Boat construction and repair.- Flexible tank welding.- Aquaculture construction and repair.- Plastic tank fabrication.- Pipe and tube welding.- Repair of plastic components like car bumpers.- Welding plastic membranes in roofing and civil engineering (geomembranes).
Industries that Commonly Use It
- Plastic Fabrication- Flooring Installer or Manufacturer- Construction/ Building Services- Marine- Automotive Service/Repair- Tarp, Fabric, Awning Manufacturing- General Manufacturing- Cladding- Pool/Spa/Plumbing
Special and Unique Features
- Bent tip design for specific access and applications.- Two-pronged design allows the welding rod to glide easily while hot air passes through the main nozzle, preventing scorching.- Designed for the "speed welding" method, which is faster than manual hot air welding.- Directs airflow precisely onto the seam.- Compatible with various Leister hot air hand tools like TRIAC ST, TRIAC AT, HOT JET S, DIODE PID/S, WELDING PEN S/R.
Key Properties
- Article Number: 156.470.- Nozzle connection diameter: 8 mm / 0.3 in.- Suitable for 5mm (Profile D ø5) welding rods.- Material: Typically crafted from good-quality stainless steel, providing excellent resistance, plasticity, and strength.- Push-fit connection.- Requires a suitable tube nozzle.
Surface Compatibility
- Polyurethane (for flooring).- PVC (Polyvinyl Chloride).- PE (Polyethylene).- PP (Polypropylene).- HDPE (High-Density Polyethylene).- LDPE (Low-Density Polyethylene).- LLDPE (Linear Low-Density Polyethylene).- TPO (Thermoplastic Polyolefin).- ECTFE (Ethylene Chlorotrifluoroethylene).- PA (Polyamide).- PC (Polycarbonate).- PVC-C (Chlorinated Polyvinyl Chloride).- PVC-U (Unplasticized Polyvinyl Chloride).- PVDF (Polyvinylidene Fluoride).- General thermoplastic materials.
Known backups / known substitutes
- Other Leister speed welding nozzles of different sizes or profiles (e.g., 3mm, 4mm, triangular, tape speed nozzles).- Leister tubular nozzles or wide slot nozzles for different welding techniques.- Nozzles from other hot air tool manufacturers (e.g., BAK, Herz, Forsthoff, Munsch, Ritmo America).- Different plastic welding methods, such as extrusion welding (for thicker materials) or manual hot air welding without a speed nozzle (pendulum welding).
Comparison Note
- Speed welding nozzles, like the Leister 156.470, enable a faster and more efficient welding process compared to traditional manual hot air welding (pendulum welding) by guiding the welding rod directly into the heated seam.- The bent tip offers specific advantages for reaching difficult areas or for particular joint designs.- They are designed for precision and consistent welds, especially for joining plastic sheets and profiles with a welding rod.
