Internal sewage reducer MAGNAPLAST HTR short 110/75 mm (model 11345)

MAGNAPLAST HTR short internal sewage reducer 110/75 mm (model 11345) is a compact PVC transition fitting designed for internal drainage systems. It provides a smooth reduction between a 110 mm soil pipe and a 75 mm branch, enabling reliable connection of pipes with different diameters in confined installation spaces. The fitting is intended for gravity drainage in residential and commercial buildings and is compatible with standard PVC sewer pipe systems.

Advantages

The short HTR design reduces the installation depth while maintaining a secure socket connection between 110 mm and 75 mm pipes. Manufactured from PVC, the reducer offers chemical resistance and low weight, simplifying handling and fitting. Its compact profile is suitable for installations with limited space and helps preserve flow characteristics across the diameter change. The product is produced to fit commonly used internal sewer systems, ensuring consistent alignment and sealing when installed according to guidelines.

Suitable for

• Connecting 110 mm soil pipes to 75 mm branches in internal drainage systems
• Residential bathroom and kitchen waste plumbing
• Commercial building drainage where space is restricted

Key specifications

• Material: PVC suitable for internal sewerage
• Inlet diameter: 110 mm (socket)
• Outlet diameter: 75 mm (socket)
• Short/compact HTR reducer design for reduced installation depth
• Type: internal sewage reducer for gravity drainage

How to use

Ensure both pipe ends are clean and free of debris before assembly. Verify that the reducer orientation matches the intended flow direction and insert the smaller and larger pipes into the respective sockets until they reach the seating mark. Use compatible solvent cement or sealing rings where required by the pipe system and local regulations to secure a watertight joint. Support adjacent pipework and check alignment to avoid undue stress on the reducer after installation. Perform a pressure or leak test according to applicable plumbing standards.

Usage recommendations

Use the reducer only in internal gravity drainage applications and avoid exposure to direct sunlight or open flame. Select appropriate joining methods and gaskets compatible with PVC sewer systems and follow local building codes for slope, support spacing, and testing. For installations in very tight spaces, verify clearances before final assembly to ensure sufficient access for maintenance.
