## Long description

SpiroFlex 125 nypel with gasket (ZU125-OC) is a 125 mm ventilation duct connector designed to join circular metal ducts in HVAC systems. The connector features an integrated gasket that provides an airtight seal between mating ducts, reducing air leakage and maintaining system pressure. It is suitable for installation in residential and commercial ventilation and air distribution systems where a secure, sealed joint is required.
Advantages
The integrated gasket ensures consistent sealing without the need for separate sealing materials, simplifying installation and improving long-term airtightness. The connector is manufactured to fit standard 125 mm circular ducts, allowing quick alignment and mechanical engagement. Its compact design facilitates use in tight spaces and supports reliable airflow by minimizing joint resistance and leakage. Materials and construction are selected to withstand normal HVAC operating conditions.
Suitable for
Connecting 125 mm circular ventilation ducts in residential buildings
Joining ducts in commercial HVAC installations and air distribution systems
Retrofit and replacement of worn or leaking duct joints
Applications requiring an integrated gasket for airtight connections
Key specifications
Nominal diameter: 125 mm
Connector type: round duct nipple with integrated gasket
Sealing: integrated elastic gasket for airtight joints
Intended use: ventilation and air distribution systems
Compatibility: designed for standard 125 mm circular metal ducts
How to use
Ensure duct ends to be joined are clean, free of sharp burrs and correctly aligned. Insert the SpiroFlex 125 nypel into the mating duct until the gasket is fully engaged and the connector sits flush. Rotate or push the connector as needed to achieve proper seating. Once positioned, secure the joint according to the installation practice for the system—this may include mechanical clamps, screws or spot welds as appropriate for the duct material and local codes. Verify the seal by inspecting the gasket contact and, if required, perform a leakage test after installation.
Usage recommendations
Use the connector with ducts of matching nominal diameter and avoid overstressing the gasket during insertion. For best results, combine with recommended mechanical fastening methods and follow local HVAC installation standards. Periodically inspect joints for damage or wear, particularly in systems subject to frequent maintenance or vibration.
