Q: What tools is this 20 mm wide-slot, 60° angled nozzle compatible with?
A: This nozzle fits handheld hot-air welders such as the BAK RiOn series and the Leister Triac S/AT models.
Q: Why is the 60° bend beneficial for a 20 mm wide-slot nozzle?
A: The angled design allows better access around membranes or roofing seams, clears obstructions and optimizes the direction of hot-air flow over the joint, improving weld consistency.
Q: What material and slot size are typical for this type of nozzle and why does that matter?
A: These nozzles are usually made of stainless steel for durability at high temperature and corrosive conditions. The 20 mm wide slot (commonly 20 × 2 mm) ensures a broad, even stream of hot air—ideal for welding thermoplastic roofing membranes like TPO or PVC.
Q: What inspection and maintenance steps should I follow to keep the nozzle functioning well?
A: After use allow the nozzle to cool fully, wipe or brush away any adhered welding residue, inspect for warping or damage to the slot or bend, ensure the push-fit attachment remains securely seated on the heat gun, and replace the nozzle if the slot deforms or airflow becomes inconsistent.
