Product Name
Leister 143.833 Screw-On Tubular Nozzle (aka Pencil Tip) for Triac & Diode 5mm Round
Brief Description
The Leister 143.833 Screw-On Tubular Nozzle is a specialized accessory designed to adapt Leister's hot air welding tools, such as the Triac ST, Triac AT, Diode S, and Diode PID, to accept M14 screw-on nozzles. This particular adapter facilitates the use of 5mm round tubular nozzles, often referred to as 'pencil tips', for precise hot air applications in plastic welding and fabrication.
Popular Applications & Uses
- Precision plastic welding, including tacking and speed welding.- Fabrication of plastic tanks, pipes, and containers.- Repair of plastic components, such as car bumpers.- Welding of roofing membranes and other waterproofing materials.- Joining of flooring materials like vinyl and linoleum.- Sealing geomembranes in civil engineering projects, including pond liners and landfill liners.- Shrinking of heat-shrink sleeves, films, and molded parts.- Forming, bending, and sealing of thermoplastic semi-finished materials.- Welding of advertising banners, tarpaulins, and inflatable plastic fabrics.- Aquaculture construction and repair.- Boat construction and repair.
Industries that Commonly Use It
- Plastic Fabrication- Construction/ Building Services- Automotive Service/Repair- Marine- Tarp, Fabric, Awning Manufacturing- General Manufacturing- Flooring Installer or Manufacturer- Pool/Spa/Plumbing- Sign & Display- Distributers & Resellers- PVC Trimboard
Special and Unique Features
- **Screw-On Design:** Ensures a secure and stable connection to compatible Leister hot air tools.- **Adapter Functionality:** Converts the tool's clamping connection (31.5mm) to an M14 thread for screw-on nozzles.- **Precision Airflow:** Designed to direct hot air precisely onto the welding seam, preventing scorching of surrounding materials.- **Durable Construction:** Made from precision-engineered stainless steel for longevity and consistent performance.- **Versatile Compatibility:** Works with a range of Leister hot air hand tools including Triac ST, Triac AT, Diode S, and Diode PID.
Key Properties
- **Material:** Precision engineered stainless steel.- **Connection Type (to tool):** Clamping connection, 31.5 mm / 1.25 inch diameter.- **Connection Type (for nozzle):** M14 screw thread.- **Nozzle Compatibility:** Specifically designed for 5mm round tubular (pencil tip) screw-on nozzles.- **Heat Resistance:** Designed to withstand high temperatures generated by hot air welding tools.- **Corrosion Resistance:** Stainless steel construction provides resistance to corrosion.
Surface Compatibility
This nozzle adapter itself does not directly contact the welding surface but enables the welding of various thermoplastic materials when used with a compatible Leister hot air tool and appropriate welding rod/filler material. Compatible surfaces include:- PVC (Polyvinyl Chloride)- HDPE (High-Density Polyethylene)- PP (Polypropylene)- ABS (Acrylonitrile Butadiene Styrene)- Thermoplastic elastomers- Modified bitumen- Coated fabrics, films, foams, and sheets- Vinyl and linoleum flooring materials
Known backups / known substitutes
- **Leister Push-Fit Nozzles:** For tools that accept push-fit nozzles, different nozzle types (e.g., standard tubular, speed welding nozzles) are available.- **Other Leister Screw-On Nozzles:** Leister offers a variety of other screw-on nozzles (e.g., triangular, drawing nozzles) that would attach to this adapter for different welding profiles and applications.- **Alternative Nozzle Adapters:** Leister produces other adapters for different nozzle sizes or angles (e.g., 30° or 45° adapters).
Comparison Note
The Leister 143.833 Screw-On Tubular Nozzle adapter is distinct from direct push-fit nozzles. It serves as an intermediary component, allowing Leister hot air tools with a 31.5mm clamping connection to utilize the M14 screw-on series of nozzles. This design provides a more secure attachment for screw-on nozzles, which can be beneficial for specific precision welding tasks or when a wider range of specialized screw-on tips is required. It is specifically designed for 5mm round tubular nozzles, making it ideal for detailed work and speed welding applications where a 'pencil tip' is preferred.
