Duct Connector SpiroFlex SX-WO80Z — galvanized ventilation spigot Ø80 mm

SpiroFlex SX-WO80Z — galvanized ventilation spigot Ø80 mm is a round duct connector designed to join sections of circular ventilation ductwork with a nominal diameter of 80 mm. Constructed from corrosion-resistant galvanized steel, this spigot provides a standard mechanical connection for residential and light-commercial HVAC systems. It is suitable for new installations, maintenance tasks and repair jobs where a robust, metal-to-metal junction is required to maintain airflow continuity and system integrity.

Advantages

The galvanized finish offers protection against rust and prolongs service life in typical indoor ventilation environments. The Ø80 mm nominal diameter matches standard small-diameter circular ducts, enabling straightforward fitting and compatibility with flexible and rigid duct sections. Its simple cylindrical design allows easy insertion and mechanical fastening using clamps, screws or sealant where required, ensuring a reliable airflow path and reduced leakage when installed correctly.

Suitable for

• Joining 80 mm circular ventilation ducts in domestic ventilation systems
• Light-commercial air distribution and exhaust connections
• Repair and replacement of damaged duct sections
• Connecting flexible ducting to rigid metal ducts

Key specifications

• Material: galvanized steel for corrosion resistance
• Nominal diameter: 80 mm (round spigot)
• Type: straight duct connector / spigot for circular ducts
• Application: indoor ventilation systems, supply and extract ducts
• Connection method: insertion-type spigot suitable for clamps, screws or sealant

How to use

Measure and prepare duct ends to ensure a snug fit with the Ø80 mm spigot. Slide the spigot into or over the mating duct section depending on the duct type (male or female ends) and align the joint. Secure the connection with an appropriate fastening method such as a metal clamp, self-tapping screws or HVAC-approved sealant to prevent air leakage. After fastening, check for leaks and ensure the airflow is not obstructed. Use appropriate personal protective equipment when cutting or handling metal ducts.

Usage recommendations

For best results, use the spigot with compatible 80 mm ducts and apply corrosion-resistant fasteners or sealant in environments with higher humidity. Avoid excessive bending or deformation during installation to maintain a tight joint and optimal airflow. Periodically inspect connections as part of routine HVAC maintenance.
