Internal sanitary sewer reducer MAGNAPLAST 160/110 short HTR gray

MAGNAPLAST short internal sanitary sewer reducer HTR 160/110 in gray is a compact PVC fitting designed to connect 160 mm to 110 mm drainage pipes inside buildings. Intended for sanitary and wastewater installations, this reducer creates a secure, space-saving transition between different pipe diameters while maintaining flow continuity and alignment. Its short design is particularly useful where installation depth or clearance is limited, such as behind fixtures or within service shafts.

Advantages

The reducer is manufactured from PVC with smooth internal surfaces to minimize flow resistance and reduce the risk of debris buildup. The short profile allows installation in confined spaces without altering the drainage slope significantly. The product is compatible with standard pressureless drainage systems and supports reliable jointing methods used in indoor sanitary installations.

Suitable for

• Connecting main soil stacks to branch pipes in residential and commercial buildings
• Toilet and bathroom drainage where a compact transition is required
• Installation inside service shafts, false walls, or ceiling voids with limited space
• Sanitary and wastewater systems that use 160 mm and 110 mm PVC pipes

Key specifications

• Material: PVC suitable for internal sanitary drainage
• Connection: reducer from 160 mm to 110 mm diameter
• Profile: short/compact design for installations with limited depth
• Colour: gray
• Application area: indoor sanitary and wastewater systems

How to use

Prepare the mating pipe ends by cutting square and deburring. Ensure both pipes are clean and dry before assembly. Fit the larger diameter end onto the 160 mm pipe and the smaller end onto the 110 mm pipe following the chosen joining method for PVC drainage (e.g., solvent welding or gasketed push-fit if compatible). Maintain the required slope for wastewater gravity flow and secure the assembly to prevent movement. After installation, test the system for leaks and proper flow according to local plumbing standards.

Usage recommendations

Use this reducer only in non-pressurized indoor drainage systems and observe local building codes. Avoid exposing the fitting to direct sunlight for prolonged periods and do not use it with aggressive chemicals unless material compatibility is verified. For best results, match pipe materials and joint types to ensure a watertight connection.
