Weld wider PVC and TPO membrane overlaps with the BAK 40 mm Wide Slot Nozzle. This push-fit hot-air welding attachment directs heat across a broad seam, making it a practical option for straight roofing membrane overlaps and suitable thermoplastic sheet work.
Why choose the 40 mm nozzle?
- Wider seam coverage: designed for standard overlap welding where a broad band of hot air is required.
- 32 mm push-fit connection: suits compatible hot-air hand welders, including appropriate BAK RiOn configurations.
- Job-specific selection: choose the 40 mm for wider seams and the 20 mm option for corners, flashings and narrow details.
Applications
Suitable for specified PVC and TPO roofing membrane overlaps, thermoplastic sheet seams and related hot-air welding applications. Follow the membrane supplier's approved welding procedure and pressure-rolling requirements.
Compatibility and ordering
BAK article 5107132. Confirm that your hand welder accepts a 32 mm push-fit nozzle before ordering; compatibility must not be assumed solely from the tool brand. Nozzle only; welding gun and pressure roller sold separately.
