Internal Sewer Reduction Coupling MAGNAPLAST HTR short 75/50 mm

MAGNAPLAST HTR short internal sewer reduction coupling 75/50 mm provides a compact, reliable transition between 75 mm and 50 mm wastewater pipes. Designed for internal soil and waste systems, this short reduction coupling is suitable for confined installation spaces and repair or retrofit works where a direct, seal-tight connection between different diameters is required. The product supports standard drainage and soil pipe materials and is intended for use in residential and commercial buildings.

Advantages

The short design reduces the space required for diameter transition while maintaining a secure mechanical and fluid-tight joint. Manufactured to compatible dimensions for common drainage systems, the coupling simplifies installation and replacement tasks. Its internal configuration allows connections to be made inside inspection chambers or in-wall installations without extending the visible pipework.

Suitable for

• Internal wastewater and soil pipe systems in residential buildings
• Commercial building drainage where space is limited
• Repair and retrofit operations to adapt from 75 mm to 50 mm pipes
• Connections inside inspection chambers, shafts, or concealed installations

Key specifications

• Function: internal sewer reduction coupling
• From diameter: 75 mm
• To diameter: 50 mm
• Design: short/compact reduction
• Intended use: internal wastewater and soil pipe systems
• Compatibility: suitable with standard drainage pipes of corresponding diameters

How to use

Ensure both pipe ends are clean and free of debris before fitting the coupling. Insert the larger pipe end into the 75 mm side and the smaller pipe into the 50 mm side, observing any manufacturer instructions for orientation and sealing. Apply a suitable sealant or gasket where required by the pipe system type to achieve a watertight connection. After installation, check alignment and test for leaks by running water through the system.

Usage recommendations

Use this short reduction coupling for internal, non-pressure wastewater applications. Verify material compatibility and local plumbing regulations before installation. For concealed or in-wall installations, allow access for future inspections and ensure joints are tested for leak-tightness after completion.
