Magnaplast sliding coupling for internal sewage HTU 50 mm (MAGNAPLAST 12210)

The Magnaplast sliding coupling for internal sewage HTU 50 mm is a mechanical connection designed for indoor wastewater and soil pipe systems. It provides a slip joint between HTU pipes with a nominal diameter of 50 mm, allowing for controlled axial movement and secure sealing in building drainage installations. The coupling is compatible with other HTU system components and is intended for use where alignment adjustments or thermal expansion compensation are required.

Advantages

This sliding coupling offers a slip/adjustable joint that facilitates easy installation and alignment of HTU pipes without the need for complex fittings. Its design supports axial movement to accommodate slight shifts or thermal expansion, while maintaining a reliable seal to prevent leaks. The coupling is made to integrate with HTU system components, ensuring dimensional compatibility and predictable performance in indoor sanitary and plumbing applications.

Suitable for

• Indoor wastewater discharge lines in residential and commercial buildings
• Soil and drain pipe connections in bathrooms, kitchens, and service rooms
• Installations requiring axial movement compensation or alignment adjustments
• Retrofit work and repairs where a slip joint simplifies replacement of short pipe sections

Key specifications

• System compatibility: HTU internal sewage system
• Nominal diameter: 50 mm
• Function: sliding/slip coupling allowing axial movement
• Suitable environment: indoor wastewater and soil pipe applications
• Main purpose: drainage pipe connection and movement compensation

How to use

Prepare the pipe ends by ensuring they are clean, free of debris, and cut square. Slide the coupling onto one pipe end and align the adjacent pipe to achieve the required engagement depth, following the HTU system installation recommendations. Allow for the designed axial movement range when positioning the pipes. After alignment, verify that the seal is correctly seated and that the coupling is fully engaged on both pipe ends. Perform a leak test according to standard plumbing practice before closing walls or concealing the installation.

Usage recommendations

Use the sliding coupling only in indoor drainage systems compatible with HTU components and within the specified nominal diameter. Avoid exposure to direct sunlight or continuous outdoor conditions. For long-term performance, ensure regular inspection access and follow local plumbing codes for pressure, temperature, and load limits.
