## Summary description

MAGNAPLAST internal sewer reducer 160/110 HTR in grey. A pipe fitting that reduces diameter from 160 mm to 110 mm for internal drainage systems. Designed for connection between larger and smaller sewer pipes, it fits HTR-type applications and facilitates smooth flow transition. Suitable for residential and commercial plumbing installations where size adaptation is required.

## Long description

MAGNAPLAST internal sewer reducer 160/110 HTR in grey is a pipe fitting designed to connect larger 160 mm sewer pipes to smaller 110 mm pipes within internal drainage systems. Its HTR designation indicates compatibility with HTR-type soil and waste systems, providing a controlled transition between differing diameters to maintain flow efficiency and reduce turbulence at the junction. The reducer is intended for installation where a reliable, compact diameter change is required inside buildings, including both new installations and retrofit work.
Advantages
The MAGNAPLAST reducer provides a secure mechanical connection between 160 mm and 110 mm pipes while preserving internal flow characteristics. Made to standard dimensions for HTR systems, it simplifies size adaptation without the need for custom machining or elaborate adapters. The grey finish allows easy visual matching with common internal sewer piping, and the compact design reduces installation space. Its smooth internal surface promotes unobstructed drainage and lowers the risk of deposit build-up at the transition point.
Suitable for
 Residential internal soil and waste drainage installations where a change from 160 mm to 110 mm diameter is required
 Commercial buildings and light industrial facilities using HTR-type piping systems
 Retrofit and renovation projects needing a space-efficient reducer inside walls or shafts
 Connections between existing larger mains and smaller branch lines within vertical stacks
Key specifications
 Material and finish: durable grey thermoplastic suitable for internal drainage

 Application area: intended for indoor soil, waste and vent piping
How to use
Before installation, verify pipe diameters and HTR compatibility. Prepare pipe ends by cleaning and deburring to ensure a proper fit. Position the reducer so the larger end mates with the 160 mm pipe and the smaller end with the 110 mm pipe; follow manufacturer guidance for alignment and insertion depth. Use the appropriate sealant or gasket and secure connections according to local plumbing codes and system requirements. Check the assembled joint for correct alignment and perform a leak test as part of system commissioning.
Usage recommendations
For reliable long-term performance, install the reducer in accessible locations where periodic inspection is possible. Avoid exposing the fitting to continuous external loads or chemical agents not compatible with standard thermoplastics. Adhere to local building regulations and HTR system installation manuals for proper venting, slope, and support to maintain efficient drainage and prevent undue stress at the junction.
