.79'' overlap nozzle with 75° degree angling for additional welding work on tarpaulins and general technical textiles. In tunnel and landfill engineering, geomembranes are stapled with this nozzle so that the films do not slide in the welding process. Furthermore, this nozzle is also used for covering roofs. In addition, this nozzle is designed for universal use and fits all hot air tools with a heating tube outer diameter of 1.24'', for example, on products of the DIODE or TRIAC series.
