Product Name
Leister 143.831 Screw-On Tubular Nozzle (aka Pencil Tip) for HotJet S
Brief Description
This product is a nozzle adapter designed for the Leister HotJet S hot air welding tool. It facilitates the use of M14 screw-fit nozzles, commonly including tubular or "pencil tip" nozzles, enabling precise hot air applications.
Popular Applications & Uses
- Precision plastic welding in confined spaces or with heat-sensitive materials.- Detail welding for applications such as end of walls, doorways, coving, inside and outside corners, toe kicks, joints, and curves.- Plastic fabrication, including welding thermoplastic materials like boards, tubes, profiles, lining membranes, films, foams, tiles, and sheets.- Shrinking of heat-shrink sleeves, films, and tapes.- Activating or dissolving solvent-free and fusion adhesives.- Drying of water-damp surfaces.- Vehicle fairing repairs.- Boat construction and repair.- Flexible tank welding.- Aquaculture construction and repair.- Pipe and tube welding.- Civil engineering and geomembrane applications, including landfill and mining membrane welding, pond and pool waterproofing, and tunnel waterproofing.
Industries that Commonly Use It
- Plastic Fabrication- Construction/ Building Services- Flooring Installer or Manufacturer- Automotive Service/Repair- Transportation/ Specialty Vehicle- General Manufacturing- Marine- Pool/Spa/Plumbing- Chemical Industry- Tarp, Fabric, Awning Manufacturing- Aerospace/Defense- Electrical Services or Products- Synthetic Turf
Special and Unique Features
- Specifically designed as an adapter for the Leister HotJet S hot air tool.- Enables the use of M14 screw-fit nozzles, offering versatility for various precision tasks.- Facilitates precise welding in confined spaces or with heat-sensitive materials when used with appropriate pencil tip nozzles.- Made from precision-engineered stainless steel, ensuring durability and consistent performance.- Features a clamping connection to the HotJet S for secure attachment.
Key Properties
- Article Number: 143.831.- Nozzle Connection Ø (to HotJet S): 21.3 mm / 0.85 in.- Nozzle Outlet Adapter Ø (for screw-on nozzles): M14 thread.- Connection Type to HotJet S: Clamping connection.- Material: Precision-engineered stainless steel (inferred from similar Leister nozzles).- Function: Adapter for screw-on nozzles.
Surface Compatibility
This adapter itself does not directly contact surfaces. Its compatibility is determined by the specific M14 screw-on nozzle attached and the material being processed by the hot air tool. The Leister HotJet S and its compatible nozzles are suitable for:- Thermoplastic materials (boards, tubes, profiles, lining membranes, coated materials, films, foams, tiles, sheets).- Single-ply flexible plastics.- Modified bitumen.- Heat-shrink sleeves, films, and tapes.- Surfaces requiring drying or adhesive activation.
Known backups / known substitutes
- Other Leister nozzle adapters designed for different nozzle types or tools.- Specific Leister push-fit nozzles if the HotJet S could be adapted for them (though 143.831 is for screw-on).- Generic hot air welding nozzles or tips from other manufacturers, though Leister recommends using only Leister accessories for optimal performance and compatibility.- Different sizes or shapes of Leister screw-on tubular/pencil tip nozzles (e.g., various diameters or angles) that fit the M14 thread.
Comparison Note
The Leister 143.831 is an essential adapter that expands the functionality of the Leister HotJet S, allowing it to utilize a range of M14 screw-on nozzles, particularly tubular or "pencil tip" styles. This differentiates it from direct-fit nozzles or adapters for other Leister tools (like TRIAC or DIODE) which may use push-fit connections. Its specific design for screw-on nozzles makes it ideal for applications requiring fine, controlled hot air streams, contrasting with wider slot nozzles used for broader welding or heating tasks.
