AKCES multi-reduction coupling socket B/K for pipes Ø50/50, Ø40, Ø32 mm, length 350 mm

The AKCES multi-reduction coupling socket B/K for pipes Ø50/50, Ø40, Ø32 mm, length 350 mm is a stepped adapter designed to join and adapt circular plastic pipes of different diameters in drainage and ventilation systems. Manufactured for situations where several diameter transitions are needed in a short run, the 350 mm coupling provides a continuous, coaxial connection that maintains alignment and flow between Ø50, Ø40 and Ø32 pipes. The product is intended for use with compatible rigid or semi-rigid plastic pipes and fittings in residential and light-commercial installations.

Advantages

The coupling offers multiple reduction steps in one component, eliminating the need for several separate adapters and reducing installation time. Its 350 mm length provides a gradual transition that helps maintain hydraulic performance and reduces turbulence at diameter changes. The B/K type design ensures secure, coaxial fit with common pipe geometries and supports straightforward insertion and sealing with standard sealing rings or solvents where applicable.

Suitable for

• Connecting drainage pipe runs with mixed diameters in residential buildings
• Adapting ventilation ducting where multiple diameters are present
• Repairing or modifying existing plastic pipe systems without replacing long sections

Key specifications

• Compatible pipe diameters: Ø50/50, Ø40, Ø32 mm
• Overall length: 350 mm
• Type: multi-reduction coupling, stepped (B/K)
• Material: durable plastic suitable for drainage and ventilation use
• Connection form: coaxial stepped socket for progressive diameter reduction

How to use

Select the appropriate end of the coupling to match the larger or smaller pipe diameter required for your installation. Prepare pipe ends by cutting square and deburring; clean contact surfaces to ensure a good seal. Insert the pipe into the corresponding socket step until it seats fully. Use the recommended sealing method for your pipe system (rubber sealing rings, adhesive or solvent welding) following pipe and sealant manufacturer instructions. Support and secure the connected pipes to prevent strain on the coupling.

Usage recommendations

Verify pipe material compatibility and sealing instructions before installation. Avoid excessive mechanical stress or bending at the coupling; provide adequate support and alignment. For drainage applications, ensure proper slope and backflow prevention as required by local regulations.
