Product Name
Leister 107.653 (ø 1.98 inch) 2.95 x 0.07 inch Wide Slot Nozzle
Brief Description
The Leister 107.653 wide slot nozzle is a precision-engineered accessory for Leister hot air tools, designed to deliver a broad and even stream of hot air. It is primarily used for efficient welding, heating, and forming of various thermoplastic materials and membranes over wider surfaces.
Popular Applications & Uses
- Welding of single-ply roofing membranes, including TPO, PVC, and EPDM.- Welding of technical textiles and industrial fabrics such as tarpaulins, tents, protective covers, and advertising banners.- Welding of geomembranes for civil engineering, landfill projects, pond, tunnel, reservoir, and canal waterproofing.- Installation and repair of vinyl and linoleum floor coverings.- Shrinking cables and heating or shaping plastic parts in the automotive industry.- General plastic repairs and fabrication tasks.- Cladding walls.- Applications involving bitumen.
Industries that Commonly Use It
- Construction/ Building Services- Plastic Fabrication- Tarp, Fabric, Awning Manufacturing- Flooring Installer or Manufacturer- Cladding- Automotive Service/Repair- General Manufacturing- Energy (for geomembrane applications)- Marine (for boat construction and repair)- Sign & Display (for banner welding)
Special and Unique Features
- Constructed from precision-engineered stainless steel for exceptional durability and high-temperature resistance.- Features a wide slot design (75 x 2 mm) to ensure efficient and uniform heat distribution over larger surface areas.- Designed with a 20° angle for targeted and precise applications, including specialized work with bitumen.- Utilizes a clamping connection for secure and stable attachment to compatible Leister hot air tools.- Optimized for use with Leister's professional range of hot air guns, such as the Triac ST/AT, Hot Jet S, and Electron ST.

Known backups / known substitutes
- Other Leister wide slot nozzles available in different dimensions (e.g., 20mm, 40mm, 60mm, 80mm, 150mm wide slot nozzles).- Wide slot nozzles produced by other compatible hot air tool manufacturers such as BAK, HERZ, Forsthoff, and SIEVERT.- Other specialized Leister nozzles designed for specific tasks, including speed welding nozzles, tubular nozzles, tacking nozzles, and sieve reflectors.
Comparison Note
This Leister 107.653 wide slot nozzle offers a broader and more uniform heat distribution compared to standard round or triangular nozzles. This characteristic makes it particularly effective for welding larger flat surfaces such as roofing membranes, tarpaulins, and flooring. It is specifically engineered for applications demanding a wider heat footprint, such as overlap welding of roofing membranes or sealing geomembranes, and is notably suitable for bitumen applications.
