## Long description

SpiroFlex Mufa 250 (oc) coupling M250-OC is designed for connecting round ducts and pipes with a nominal diameter of 250 mm. The coupling provides a mechanical connection that ensures alignment and a continuous airflow path for HVAC and ventilation systems. Suitable for use in residential and commercial installations, this component supports straightforward joining of duct sections while preserving the geometry and airflow characteristics of the duct run.
Advantages
The coupling offers a simple mechanical join that reduces installation time and keeps duct sections aligned without the need for extensive sealing materials. Its construction maintains a smooth internal profile to minimise airflow resistance and helps to preserve airtightness when installed with appropriate sealing methods. The coupling’s design accommodates standard round duct ends and supports reliable mechanical fixation between adjoining sections.
Suitable for
 Connection of round ventilation ducts with 250 mm nominal diameter
 HVAC and air distribution systems in residential buildings
 Commercial ventilation and mechanical exhaust systems
 Repair or modification of existing ductwork runs
Key specifications
 Compatible nominal diameter: 250 mm
 Type: round duct coupling for mechanical connection
 Application: ventilation, HVAC, air distribution
 Function: alignment and mechanical joining of duct sections
 Suitable for use in residential and commercial installations
How to use
Prepare the duct ends by ensuring they are clean, free of burrs and correctly cut to the required length. Slide the coupling onto one duct end and align the adjoining duct section so the coupling fully overlaps both ends. Secure the connection using the recommended mechanical fasteners or clamps and apply a compatible sealing method—such as sealing tape or duct sealant—if airtightness is required. Verify alignment and airflow path before completing the installation.
Usage recommendations
Use the coupling with ducts that match the nominal 250 mm diameter and check that ends are undamaged for proper fit. For installations requiring low leakage, combine the mechanical coupling with appropriate sealing materials and follow local ventilation standards. Periodically inspect connections as part of routine HVAC maintenance to ensure continued performance.
