MAGNAPLAST internal sewage reducer HTR 75/50 mm (model 11320)

MAGNAPLAST internal sewage reducer HTR 75/50 mm is a pipe fitting for connecting 75 mm and 50 mm drainage lines in internal plumbing systems. It creates a sealed, concentric transition between different diameters to ensure reliable wastewater flow in bathrooms, kitchens and utility spaces. The reducer is intended for use with compatible plastic wastewater pipes and simplifies repairs, renovation work and new installations where a diameter change is required.

Advantages

The reducer provides a compact and durable solution for connecting different pipe diameters without additional adapters. Its design ensures a tight fit that reduces the risk of leaks and supports smooth flow from larger to smaller drains. Installation is straightforward and does not require complex tools, making it suitable for both professional plumbers and experienced DIY users. The fitting is resistant to typical household wastewater conditions and maintains stable performance over time.

Suitable for

• Connecting 75 mm to 50 mm internal wastewater pipes
• Bathroom and toilet drain transitions during renovation or repair
• Kitchen sink drain adaptations to existing drainage systems
• Utility room installations where pipe diameter reduction is needed

Key specifications

• Connection diameters: 75 mm to 50 mm
• Application area: internal wastewater/drainage systems
• Compatibility: intended for use with compatible plastic wastewater pipes
• Function: concentric reducer for sealed transition between diameters

How to use

Ensure both pipe ends are clean, free of debris and cut squarely. Slide the reducer onto the larger pipe or into the corresponding socket according to the system requirements, then insert the smaller pipe into the opposite end until fully seated. Check for correct alignment and seating to maintain a concentric connection. Secure connections as required by the piping system—use appropriate solvent, sealant or compression fittings only if compatible with the pipe materials and local plumbing standards. After installation, run a water test to confirm there are no leaks at the joints.

Usage recommendations

Use the reducer only with compatible plastic wastewater pipes and joints. Follow local plumbing codes and manufacturer guidance for sealing and securing connections. For long-term reliability, inspect joints after the first period of use and recheck after any structural modifications or heavy loads on the drainage system.
