Product Name
Leister 105.431 Narrow Preheat 0.12" / 3mm Round Speed Welding Nozzle
Brief Description
This Leister 105.431 nozzle is a specialized accessory designed for hot air plastic welding tools, specifically for "speed welding" applications. It features a narrow preheat design and a 3mm round outlet, optimized for fast and efficient joining of plastic materials using a welding rod. It is compatible with Leister Triac ST, Triac AT, and Diode PID/S hot air hand tools.
Popular Applications & Uses
- High-speed precision plastic welding.- Repair of various plastic items such as agricultural, harvest, and automotive bins.- Welding of polyurethane and PVC protected floors (vinyl and linoleum).- Repairing plastic components like car bumpers and kayaks.- Long weld runs in plastic fabrication.
Industries that Commonly Use It
- Construction/ Building Services- Flooring Installer or Manufacturer- Plastic Fabrication- Automotive Service/Repair- Marine- PVC Trimboard- General Manufacturing
Special and Unique Features
- Narrow preheat design for precise heat application.- 3mm round outlet for use with corresponding round welding rods.- "Speed welding" capability for fast processing of long weld runs.- Two-pronged design allows the welding rod to glide easily while hot air passes through the main nozzle, directing airflow directly onto the seam and preventing scorching.- Push-fit connection for easy attachment to compatible Leister hot air tools.
Key Properties
- Nozzle Connection Ø: 8 mm / 0.3 in (for attachment to the hot air tool).- Outlet Diameter: 3mm / 0.12" round.- Material: Typically stainless steel for durability and heat resistance.- Compatibility: Designed for Leister Triac ST, Triac AT, and Diode PID/S hot air tools.- Function: Directs hot air and guides welding rod for efficient plastic welding.
Surface Compatibility
- Polyurethane- PVC (vinyl, linoleum, PVC packing)- Various thermoplastics (e.g., for bins, kayaks, car bumpers)- Other plastics compatible with hot gas welding techniques (e.g., nylon, polyethylene, ABS, acrylic, polypropylene, fluoropolymers, some elastomers).
Known backups / known substitutes
- Other Leister speed welding nozzles with different profiles (e.g., 4mm round, triangular, tape speed nozzles) depending on the welding rod and application.- Standard nozzles used for pendulum welding for shorter runs or difficult access.- Tacking nozzles for ensuring close joint interfaces and alignment.- Wide slot nozzles for broader applications.- Different brands of hot air welding nozzles, provided they are compatible with the specific hot air tool.
Comparison Note
The Leister 105.431 Narrow Preheat 0.12" / 3mm Round Speed Welding Nozzle is specifically designed for speed welding, offering a faster process compared to pendulum welding for long weld runs. Its narrow preheat and 3mm round profile make it ideal for precise work with corresponding round welding rods. While other nozzles exist for tacking, wide slots, or different rod profiles, this nozzle excels in applications requiring efficient, continuous seam welding of plastics, particularly in flooring and plastic fabrication where a consistent, narrow bead is desired.
