Ricom elbow PP-AL 87° DN80/125 with inspection and gasket (model PP80/125RB)

Ricom elbow PP-AL 87° DN80/125 with inspection and gasket (model PP80/125RB) is a dual-layer ventilation fitting combining a polypropylene inner surface with an aluminum outer layer. The component provides an 87-degree directional change for duct sections sized DN80/125 and incorporates an access inspection port plus a compressible gasket to ensure sealed joints. It is designed for use in both commercial and residential HVAC ductwork where a compact angled transition and reliable sealing are required.

Advantages

The polypropylene-aluminum construction offers a balance of chemical resistance, smooth airflow and mechanical protection. The integrated inspection port allows visual checks and maintenance access without disassembling adjoining duct sections. A supplied gasket simplifies installation by providing an immediate seal at the connection points, reducing the risk of air leaks and improving system efficiency. The 87° geometry enables tighter routing where a near-right-angle change is needed while maintaining consistent internal diameter for DN80/125 systems.

Suitable for

• HVAC duct runs requiring an angled transition at DN80/125 diameter
• Rectangular-to-round transitions and compact routing in ventilation systems
• Residential and light commercial ventilation projects needing inspection access

Key specifications

• Angle: 87° directional bend
• Nominal diameter compatibility: DN80/125
• Construction: polypropylene inner layer with aluminum outer layer
• Includes integrated inspection port for access and monitoring
• Provided gasket for sealed connection at joints
• Designed for ducting in HVAC ventilation systems

How to use

Position the elbow in the duct run at the required change of direction for DN80/125 piping. Ensure adjoining duct ends are clean and free of debris before assembly. Fit the gasket into the connection groove and insert the mating duct section until the joint is fully engaged. Use the inspection port to verify internal alignment and to perform visual inspections or minor maintenance without dismantling adjacent fittings. Secure the connection using appropriate clamps or fastening methods suitable for the ventilation system in use, following local installation standards.

Usage recommendations

Install the elbow in accessible locations where the inspection port can be reached for periodic checks. Verify compatibility with system airflow rates and temperature limits typical for polypropylene-aluminum duct components. Avoid exposing the fitting to direct heat sources or harsh chemicals beyond material specifications, and ensure joints are properly sealed to maintain ventilation efficiency.
