Elbow fitting Ricom PP-AL 87° DN60/100 for pipe connection

The Ricom PP-AL 87° elbow fitting DN60/100 is a compact composite connector intended for changing direction in ventilation and ducting systems. Constructed from PP-AL (polypropylene-aluminium) material, the elbow provides a transition between DN60 and DN100 pipe diameters while offering corrosion resistance and low weight. Its 87-degree bend gives a near-right-angle redirection that suits constrained installations where a smooth, reliable joint between dissimilar duct sizes is required.

Advantages

The PP-AL composite construction combines the chemical resistance and lightness of polypropylene with the dimensional stability provided by an aluminium layer. This results in a fitting that resists corrosion, is easy to handle during installation, and maintains shape under normal ventilation loads. The 87° geometry reduces flow disruption compared with sharper bends and facilitates a compact installation footprint when connecting DN60 to DN100 ducts.

Suitable for

• Residential and commercial ventilation systems requiring a change of direction between DN60 and DN100 ducts
• Ducting installations in confined spaces where a compact 87° turn is needed
• Applications where corrosion resistance and low component weight are preferred

Key specifications

• Material: polypropylene with aluminium layer (PP-AL composite)
• Angle: 87° bend for near-right-angle redirection
• Connection diameters: designed to join DN60 to DN100 ducts
• Typical use: ventilation and ducting applications
• Properties: corrosion-resistant, lightweight, dimensionally stable

How to use

Align the Ricom PP-AL 87° elbow between the DN60 and DN100 duct ends, ensuring proper seating of each mating pipe into the corresponding end of the fitting. Secure connections using appropriate clamps or seals compatible with PP-AL material and the duct system being used. Ensure joints are aligned to maintain airflow direction; avoid excessive mechanical stress on the fitting during tightening. After installation, inspect the junction for gaps and verify that the elbow orientation provides the required airflow path.

Usage recommendations

For reliable performance, use compatible DN60 and DN100 ducts and sealing methods recommended for PP-AL components. Avoid exposure to temperatures or chemicals outside the material specifications of polypropylene. During planning, consider the slight deviation from a perfect 90° turn when calculating duct lengths and airflow characteristics.
