Full Description

The 150mm EN1401 Level Invert Reducers are designed to facilitate smooth transitions between 150mm pipes and smaller diameter connections in structured wall drainage systems. Available in two configurations — 150mm to 110mm and 150mm to 160mm — these reducers maintain a consistent invert level, ensuring uninterrupted flow and preventing blockages.

Manufactured from high-strength twin wall polypropylene, they are SN8-rated for long-term performance and compatibility with Metro Sewer pipe systems. Ideal for use in adoptable and private foul water systems, the reducers provide a watertight seal when used with Metro Sewer couplers and elastomeric seals.
