Coupling SpiroFlex SpiroFlex Mufa MF D-200 – pipe coupling D-200 for ventilation and ducting

SpiroFlex Mufa MF D-200 is a round pipe coupling designed to join D-200 diameter ventilation ducts and pipe sections. It provides a mechanical connection that ensures alignment and a secure fit between circular HVAC components. Developed for use in residential, commercial and light industrial ventilation systems, the coupling is intended to simplify installation and maintain continuity of airflow in ductwork runs.

Advantages

The coupling offers a reliable mechanical joint that helps preserve duct alignment and reduces the risk of air leakage when installed correctly. Its circular D-200 design matches standard round ventilation pipes, facilitating straightforward connection without additional shaping or modification. The product supports repeatable assembly and disassembly for maintenance or system changes, and its simple geometry allows compatibility with common duct sealing and fastening methods.

Suitable for

• Connecting round ventilation ducts with D-200 diameter
• Repairing or extending existing HVAC duct runs
• Residential and commercial ventilation installations
• Light industrial air distribution systems

Key specifications

• Nominal diameter: D-200 (designed for 200 mm round ducts)
• Function: mechanical coupling for circular ventilation ducts
• Compatibility: standard round HVAC duct profiles of matching diameter
• Typical materials: metal or reinforced materials suitable for ductwork (verify material with supplier)
• Mounting: designed for mechanical fastening and sealing with standard clamps, screws or duct sealant

How to use

Position the SpiroFlex Mufa MF D-200 so each duct end inserts evenly into the coupling until alignment is achieved. Ensure mating duct ends are clean and free of debris before assembly. Secure the joint using appropriate clamps, screws or approved duct sealant according to local installation practices and the duct material. After fastening, check the connection for alignment and perform an air-tightness check as part of commissioning to confirm there are no significant leaks.

Usage recommendations

Use compatible clamps and sealants rated for ventilation systems, and follow local HVAC installation standards. Verify the coupling material and any corrosion protection are suitable for the operating environment. For optimal performance, inspect joints periodically and reseal or retighten fastenings if necessary.
