Product Name
Leister 100.303 Tubular Nozzle (aka Pencil Tip) for Triac & Diode 5mm Round
Brief Description
The Leister 100.303 Tubular Nozzle, also known as a Pencil Tip, is a precision-engineered, 5mm round, push-fit stainless steel accessory designed for use with Leister Triac and Diode hot air welding tools. It serves as a fundamental component for various hot air applications, particularly in plastic welding and heating tasks requiring focused heat.
Popular Applications & Uses
- Plastic welding of thermoplastic materials such as PVC, PE, and PP.- General plastic fabrication and repair.- Tacking preparation and setting materials in place before final welding.- Welding of vinyl flooring and other resilient flooring installations.- Roofing membrane welding and waterproofing applications.- Civil engineering projects, including geomembrane sealing for landfill liners and tunnels.- Heat shrinking applications for tubing, electrical interconnection devices, and molded parts.- Repair of automotive components like car bumpers.- Heat sealing of single-ply flexible plastics, lining membranes, coated materials, films, foams, and sheets.- Joining billboards and flex banners.- Heating components for bending, coupling, and forming.- Activating hot melt adhesives.
Industries that Commonly Use It
- Plastic Fabrication- Construction/ Building Services (including roofing, civil engineering, and geomembrane installation)- Flooring Installer or Manufacturer- Automotive Service/Repair- Electrical Services or Products- General Manufacturing- Sign & Display- Tarp, Fabric, Awning Manufacturing
Special and Unique Features
- Constructed from precision-engineered stainless steel for durability and consistent performance.- Features a push-fit design, allowing for quick and secure installation and removal without the need for additional tools.- Its 5mm round diameter is ideal for detailed work and welding smaller plastic components where precise heat control is crucial.- Delivers consistent heat distribution, which is essential for achieving reliable and high-quality welding results.- Highly versatile, functioning effectively for free-style (pendulum) welding and as an adapter for various speed welding nozzles.- Specifically designed for broad compatibility with Leister hot air tools, including the Triac ST, Triac AT, Diode PID/S, Triac S, Hot Jet S, and Labor S models.
Key Properties
- Material: Stainless steel- Nozzle Type: Tubular / Pencil Tip- Pipe Diameter: 5mm- Connection Type: Push-fit / Clamping connection (for Ø 31.5 mm / 1.25 in nozzle connection)- Compatibility: Designed for Leister Triac series (ST, AT, S), Diode series (PID/S), Hot Jet S, and Labor S hot air tools.- Angle: 15° (where specified in technical data)- Pipe Length: 37mm (where specified in technical data)
Surface Compatibility
- Thermoplastic materials, including PVC, PE, PP, ABS, and HDPE.- Vinyl and linoleum surfaces.- Various roofing membranes, particularly single-ply flat roof membranes.- Geomembranes and other lining membranes.- Coated materials, films, foams, and sheets.- Composites.
Known backups / known substitutes
- Other Leister tubular nozzles of varying diameters or specialized designs, such as tacking nozzles, speed welding nozzles, or wide slot nozzles, can serve as alternatives depending on the specific application.- Generic or aftermarket 5mm tubular nozzles compatible with Leister hot air tools may be available, though genuine Leister nozzles are generally recommended for optimal performance, fit, and durability.- Specific Leister nozzles like the 107.154 for Ghibli or 107.144 for HOT JET S & LABOR S are designed for particular tool models.
Comparison Note
The Leister 100.303 Tubular Nozzle stands out as a versatile, standard accessory, often serving as a foundational component for attaching various speed welding nozzles. It excels in delivering precise, focused heat for detailed work and tacking operations. This distinguishes it from wider slot nozzles, which are designed for broader heat distribution, and specialized speed welding nozzles, which are optimized for faster, more consistent seam welding when used with a welding rod. Its push-fit connection offers significant convenience for quick interchangeability compared to screw-on nozzle types.
