1. Measure and Cut
Measure the length of the pipe and cut to the required size using an angle grinder. Make sure the cut is straight and clean to ensure a tight fit with adjoining sections.
2. Seal the Male End
Apply a suitable duct sealant around the male end of the spiral pipe. This is the end designed to slide into the next section.
3. Insert the Male Connector
Slide the male connector (or "spigot”) into the pipe. This will ensure a tight, streamlined transition between duct sections.
4. Secure the Connection
Use self-tapping screws to fix the duct sections to the connector. Space the screws evenly around the circumference. After screwing, wrap the joint with quality duct tape (e.g., aluminium foil tape) to further seal the connection and reduce air leakage.
5. Inspect for Leaks
Once all joints are sealed, check the entire duct run for air leaks or loose fittings
