Product Name
Leister 113.876 3mm (0.12 in) Round Screw-On Speed Welding Nozzle (without tacking tip)
Brief Description
The Leister 113.876 is a precision-engineered stainless steel screw-on speed welding nozzle designed for use with compatible Leister hot air welding tools. It features a 3mm round profile and is specifically crafted for the efficient and rapid welding of plastic materials using the speed welding technique. This nozzle facilitates continuous, long weld runs by simultaneously directing hot air and guiding the welding rod.
Popular Applications & Uses
- Speed welding of plastic sheets, pipes, and profiles- Fabrication and repair of plastic components- Installation and repair of PVC and polyurethane protected flooring (vinyl and linoleum)- Roofing membrane welding- Construction and repair in marine environments, such as boat and aquaculture structures- Plastic tank fabrication- Repair of plastic items like car bumpers and various types of bins- Welding of tarpaulins and coated fabrics
Industries that Commonly Use It
- Plastic Fabrication- Construction/ Building Services (including roofing and general building plastics)- Flooring Installer or Manufacturer- Marine (for boat and aquaculture construction/repair)- Automotive Service/Repair (for plastic component repair)- General Manufacturing (for plastic component assembly and repair)- Chemical Industry (for plastic tank fabrication)- Pool/Spa/Plumbing (for plastic pipe welding)- Fabrication (general plastic fabrication tasks)- Tarp, Fabric, Awning Manufacturing
Special and Unique Features
- **Speed Welding Design:** Engineered for fast processing of long weld runs, enhancing productivity.- **Screw-On Connection:** Ensures a secure and stable attachment to compatible Leister hot air tools.- **Precision-Engineered:** Made from high-quality stainless steel for durability and consistent performance.- **Optimal Airflow and Rod Guidance:** Two-pronged design allows the welding rod to glide smoothly while hot air is directed precisely onto the seam, preventing scorching.- **Without Tacking Tip:** Designed specifically for the main welding stage, assuming prior tacking or for applications where tacking is not required.
Key Properties
- **Material:** Stainless steel- **Nozzle Connection:** Screw-on (M14)- **Welding Rod Compatibility:** 3mm (0.12 in) round welding rods- **Nozzle Profile:** Round, 3mm diameter- **Function:** Directs hot air and guides welding rod for speed welding- **Compatibility:** Designed for specific Leister hot air hand tools (e.g., TRIAC, DIODE, HOT JET S, LABOR S, PENWELD S)
Surface Compatibility
This nozzle is compatible with various thermoplastic materials that can be hot-air welded, including but not limited to:- PVC (Polyvinyl Chloride)- Polyurethane- Linoleum- Other weldable plastics used in fabrication, roofing, flooring, and marine applications.
Known backups / known substitutes
- **Other Leister Speed Welding Nozzles:** Available in different sizes (e.g., 4mm, 5mm round) or profiles (e.g., triangular) to suit various rod diameters and joint designs.- **Leister Tacking Nozzles:** Used for initial tacking of plastic parts before the main weld.- **Leister Wide Slot Nozzles:** For broader heating applications or different welding techniques.- **Leister Tubular Nozzles:** Standard nozzles onto which speed welding nozzles often push-fit or screw-on.- **Nozzles from other hot air welding equipment manufacturers:** May serve similar functions but require compatibility checks with the specific welding tool.
Comparison Note
The Leister 113.876 stands out as a specialized speed welding nozzle, optimized for efficiency in long, continuous plastic welds with 3mm round rods. Unlike general-purpose or tacking nozzles, its design prioritizes rapid material deposition and consistent seam quality for specific applications like flooring, roofing, and plastic fabrication. Its screw-on connection offers a secure fit compared to some push-fit alternatives, ensuring stability during demanding tasks. The absence of a tacking tip means it's focused purely on the welding process, often used after initial tacking has been performed with a different nozzle.
