Multi-reducer Coupling AKCES for Pipes Ø50/40/32 mm, Length 350 mm

AKCES multi-reducer coupling for pipes Ø50/40/32 mm, length 350 mm is a single-piece transition element that allows connection of circular pipes with three different diameters. The coupling provides a sequential reduction from Ø50 to Ø40 to Ø32 mm in one component, enabling smooth airflow or fluid flow continuity in ventilation, drainage and plumbing systems. It is intended for use in retrofit, repair and extension tasks where matching different pipe sizes is required without multiple separate adapters.

Advantages

The coupling combines three reduction steps in a single molded part, reducing the number of joints and potential leak points. Its 350 mm length offers gradual transition between diameters, which helps maintain flow characteristics and reduces turbulence. Designed for quick installation, the component simplifies stocking and selection when multiple pipe sizes are present. The plain circular profile ensures compatibility with standard round ducts and pipes of the stated diameters.

Suitable for

• Ventilation ducts requiring sequential diameter reduction
• Drainage or waste pipe adaptations in renovation works
• Plumbing system extensions where multiple sizes must be joined
• Temporary or permanent repairs that avoid multiple couplings

Key specifications

• Compatible diameters: Ø50 mm, Ø40 mm and Ø32 mm
• Overall length: 350 mm
• Type: multi-reducer coupling for circular pipes
• Application areas: ventilation, drainage, plumbing systems
• Connection style: sequential single-piece transition between diameters

How to use

Measure and confirm pipe diameters before installation to ensure compatibility with Ø50, Ø40 and Ø32 mm ends. Clean pipe ends and remove debris to provide proper contact surfaces. Insert the larger pipe end onto the corresponding coupling section and secure as required by the system—use clamps, adhesive or sealing tape according to the material and local practice. Progressively attach the intermediate and smaller diameter pipes to the respective sections until all connections are complete. Verify alignment and perform a leak or airflow check after installation.

Usage recommendations

For best results use the coupling in applications where a single-piece sequential reduction improves reliability and reduces the number of joints. Select appropriate sealing or fastening methods compatible with the pipe material and the operating conditions of the system. Avoid excessive bending or mechanical stress at the coupling; support adjacent pipe runs to preserve alignment and seal integrity.
