Product information

Description

SpiroFlex 125 mufa (oc) is a duct connector designed for Ø125 mm round ventilation and air-conditioning ducts. The connector provides a straightforward mechanical coupling between circular metal ducts, maintaining alignment and a continuous airflow path. It is intended for HVAC installations, ductwork extensions and repair work in residential and commercial ventilation systems, offering a compact and compatible solution for joining standard 125 mm ducts.

Advantages

The connector delivers a stable mechanical joint that reduces the risk of misalignment and air leakage at duct connections. Its geometry is made to match Ø125 mm round ducts, enabling quick assembly without complex tools. The product supports reliable airflow continuity and is suitable for repeated installation and removal when access or maintenance is required.

Suitable for

Joining Ø125 mm round metal ventilation ducts
HVAC installation and commissioning
Duct repairs and section replacements
Extending existing ventilation runs
Temporary or permanent duct connections in residential and commercial systems

Key specifications

Nominal diameter: Ø125 mm round ducts
Function: mechanical connector for circular metal ducts
Application: ventilation and air-conditioning ductwork
Compatibility: standard 125 mm round duct profiles
Construction: designed for repeated assembly and disassembly

How to use

Align the two duct ends to be joined and slide the SpiroFlex 125 mufa (oc) over the mating profiles until fully seated. Ensure concentric alignment so the connector fits evenly around both duct ends. Secure the joint as required by the installation method—this may include applying screws, clamps or sealing tape according to local practice and airtightness needs. Verify the connection visually and by hand to confirm stable seating and absence of gaps that could cause leakage.

Usage recommendations

For best results, use the connector with matching Ø125 mm metal ducts and follow local ventilation installation standards. Where airtightness is required, complement the mechanical joint with suitable sealing (foil tape, mastic) and fasteners. Inspect joints after installation and during maintenance to ensure continued alignment and leak-free performance.
