Product Name
Leister 105.432 Narrow Preheat 0.16" - 4mm Round Speed Welding Nozzle
Brief Description
This is a precision-engineered stainless steel speed welding nozzle designed for use with Leister hot air tools (such as TRIAC and HOT JET S series) to facilitate fast and efficient plastic welding, particularly for long weld runs. It features a narrow preheat slot and accepts 4mm round welding rods.
Popular Applications & Uses
- Speed welding of vinyl flooring- Welding polyurethane and PVC protected floors (e.g., linoleum)- Fast processing of long plastic weld runs- Precision plastic fabrication and repair
Industries that Commonly Use It
- Flooring Installer or Manufacturer- Construction/ Building Services- Plastic Fabrication- General Manufacturing (where plastic welding is performed)
Special and Unique Features
- **Speed Welding Design:** Engineered for continuous, efficient, and fast welding of long seams.- **Narrow Preheat Slot:** Helps to plasticize the filler material for precise and high-quality results.- **Push-fit Connection:** Designed for easy attachment to compatible 5mm tubular nozzles on Leister hot air guns.- **Precision Engineered Stainless Steel:** Ensures durability and consistent performance.- **Integrated Air Slide:** Features a small air slide for controlled airflow.
Key Properties
- **Material:** Precision engineered stainless steel.- **Nozzle Connection Diameter:** 8 mm / 0.3 inches (for the nozzle itself)- **Welding Rod Compatibility:** Accepts 4mm round welding rods (Profile D ø4).- **Required Base Nozzle:** Requires a 5mm round tubular nozzle (e.g., Leister 100.303 for TRIAC/DIODE, 107.144 for HOT JET S/LABOR S).- **Connection Type:** Push-fit.- **Airflow:** Directs hot air directly onto the seam, preventing scorching of edges.
Surface Compatibility
- Polyurethane protected floors- PVC protected floors (vinyl and linoleum)- Various thermoplastic materials suitable for hot air welding
Known backups / known substitutes
- Other Leister speed welding nozzles for different rod profiles (e.g., 3mm round, 5mm round, triangular profiles).- Leister 106.990 (another 4mm round speed weld nozzle).- Different types of plastic welding nozzles depending on the application (e.g., tacking nozzles, tubular nozzles, wide slot nozzles).
Comparison Note
This Leister 105.432 nozzle is specifically designed for speed welding with 4mm round rods, offering efficiency for long weld runs, particularly in flooring applications. Its narrow preheat slot and push-fit design distinguish it for precise and fast work when compared to general-purpose or tacking nozzles. It requires a compatible 5mm tubular nozzle for attachment to the hot air tool.
