When a job demands a tight, controlled stream of heat, the **Steinel 20mm nozzle** delivers. Its flat, angled 20×2 mm mouth concentrates airflow so lap welds on roofing membranes, tarpaulins and plastic sheet fuse cleanly without scorching adjacent material. The geometry helps you reach corners and edges, aligning with the work so you can keep the gun moving at a steady pace. Pair it with HG 2520 E or HG 2620 E‑class tools and you get a stable, predictable weld line that stands up to site inspection. Contractors value the nozzle’s durable build and positive screw‑on fit that resists spin under vibration. Whether you are stitching long seams on EPDM, detailing around outlets or repairing punctures, the **Steinel 20mm nozzle** lets you place heat exactly where it belongs—consistent feed, tidy bead, and fewer reworks.
