MAGNAPLAST elbow external D200x90/87° pipe fitting 23140

MAGNAPLAST elbow external D200x90/87° pipe fitting 23140 is an external elbow designed for connecting round ducts with a nominal diameter of 200 mm and changing the duct direction by approximately 90° (87° effective angle). The component is intended for use in ventilation and ductwork systems where a compact external bend is required to route airflow while preserving cross-sectional flow area and ensuring stable mechanical connection with matching D200 system parts.

Advantages

The external elbow provides a precise angle for directional changes and is manufactured to fit D200 system components, ensuring consistent diameter alignment and reduced leakage at joints. Its external configuration simplifies installation in systems where internal bends are impractical, and the smooth curvature supports airflow continuity with minimal local turbulence. The fitting’s geometry facilitates secure mechanical connections and straightforward integration into existing duct runs.

Suitable for

• Ventilation ducts with a 200 mm nominal diameter
• Ductwork routing where an external 90° bend is required
• Commercial and residential HVAC systems using D200 components
• Repair or extension of existing circular duct runs

Key specifications

• Nominal diameter: 200 mm
• Angle: 90° nominal (87° effective)
• Type: external elbow for round ducts
• Compatibility: designed for D200 duct system components

How to use

Prepare the mating duct ends by ensuring clean, undamaged edges and remove any debris or burrs. Align the elbow with the D200 duct sections so that the diameters match and the elbow’s external profile sits flush. Insert and secure connections according to the system’s fastening method—this may include clamps, screws, or sealants compatible with the duct material. Verify alignment and seal integrity after installation and perform a pressure or leak check as appropriate for the ventilation system.

Usage recommendations

When installing the elbow, follow local building codes and HVAC best practices. Use appropriate gaskets or sealants where necessary to minimize air leakage, and avoid sharp bends or compression of the duct that could reduce flow. For long runs or high-velocity systems, consider supporting the elbow to prevent stress on adjacent duct connections.
