Sliding Coupling Internal Drainage Low Noise 110 mm MAGNAPLAST 146670

The Sliding Coupling Internal Drainage Low Noise 110 mm MAGNAPLAST 146670 is a coupling designed for internal drainage systems using 110 mm pipes. It features a low-noise construction that reduces vibration and sound transmission in wastewater and drainage lines. The coupling permits axial movement and compensates for minor misalignment during installation and thermal expansion, providing a stable and quiet connection between pipe segments in residential and commercial buildings.

Advantages

The low-noise design minimizes sound propagation through the drainage network, improving acoustic comfort in occupied spaces. Its sliding mechanism allows for axial displacement and slight angular correction, which simplifies installation and reduces stress on joints caused by temperature changes or building movement. The product provides a secure seal to prevent leaks while remaining compatible with standard 110 mm internal drainage pipes.

Suitable for

• Internal wastewater and drainage systems in residential buildings
• Internal drainage installations in commercial and public buildings
• Renovation projects where existing pipes require connection with allowance for movement
• Installations requiring reduced noise transmission from wastewater flow

Key specifications

• Nominal pipe diameter: 110 mm
• Type: sliding coupling for internal drainage
• Noise reduction: low-noise construction to limit vibration and sound transfer
• Movement compensation: allows axial movement and minor misalignment correction
• Sealing: integrated sealing elements for leak prevention
• Material: durable polymer designed for wastewater applications
• Compatibility: suitable with standard 110 mm internal drainage pipes and fittings

How to use

Prepare pipe ends by ensuring they are clean, free of burrs and correctly cut to standard dimensions. Slide the coupling onto one pipe end, align the mating pipe and allow the sliding mechanism to engage; ensure sealing elements are seated properly. Push the pipes together while maintaining alignment; the coupling will permit slight axial adjustment during final positioning. Verify the connection integrity and test the system for leaks before completing the installation and closing access panels.

Usage recommendations

Use the coupling in accessible sections of the internal drainage system to allow inspection and maintenance. Avoid exposing the product to prolonged direct sunlight or aggressive chemical agents not specified for wastewater systems. For reliable acoustic performance, combine with appropriate pipe support spacing and vibration-isolating hangers where needed. Follow local building codes and installation standards for internal drainage.
