Flue Adaptor WADEX ADAPTOR FLUE D143/150 — pipe transition D143 to D150

WADEX ADAPTOR FLUE D143/150 is a flue pipe adaptor designed to join duct sections with nominal diameters of 143 mm and 150 mm. Constructed for use in ventilation, heating and appliance flue systems, the adaptor provides a concentric transition that maintains airflow continuity and helps achieve a secure mechanical fit between differing pipe sizes.

Advantages

The adaptor is engineered for straightforward mechanical connection and stable alignment between 143 mm and 150 mm ducts. Its shape reduces turbulence at the junction, supporting uninterrupted exhaust or ventilation flow. The component is compatible with standard metal flue and ventilation pipes and enables a tight fit when combined with appropriate clamps or sealing methods.

Suitable for

• Connecting flue or exhaust pipes where a transition from 143 mm to 150 mm diameter is required
• Heating appliance flues and boiler exhaust ducts
• Ventilation duct runs that require step changes in pipe diameter
• Repairing or modifying existing ductwork to fit available pipe sizes

When it may not be suitable

This adaptor is intended for matching specific nominal diameters (143 mm to 150 mm) and may not fit non-standard or proprietary pipe profiles. It is not a sealing system by itself; for gas-tight or high-temperature applications additional sealing, gaskets or approved connectors may be required according to local building codes and appliance manufacturer instructions.

Key specifications

• Type: concentric flue/duct adaptor (step transition)
• Input diameter: 143 mm (nominal)
• Output diameter: 150 mm (nominal)
• Typical applications: ventilation, heating flue, appliance exhaust

How to use

Insert the smaller and larger pipe ends into the corresponding adaptor ends ensuring full engagement. Align the adaptor concentrically to avoid abrupt flow disturbances. Secure connections with suitable clamps, screws or approved sealing material where required by the installation. After fitting, verify alignment and mechanical stability and check for leaks or gaps if the system requires airtightness.

What to consider before purchase

• Verify actual outside diameters and pipe profile to ensure compatibility with nominal 143 mm and 150 mm sizes
• Check whether the installation requires gas-tight or high-temperature rated connectors and additional seals
• Confirm material compatibility with the existing ductwork and the operating environment (corrosion, temperature)

Usage recommendations

Use the adaptor in combination with appropriate clamps or sealing methods and follow appliance manufacturer and local building code requirements for flue and ventilation installations. Regularly inspect fitted joints for corrosion, loosened fasteners or degradation of seals.
