The 160 - 110mm Underground uPVC Level Invert Reducer is an essential transition fitting designed to connect different pipe sizes within below-ground gravity drainage and sewerage networks. Manufactured from tough, high-impact unplasticized polyvinyl chloride, this reducer is engineered to withstand heavy external soil loads, ground movement, and corrosive subterranean environments, ensuring long-term structural reliability and performance across varying pipe diameters.
 
Featuring a level invert design, this component ensures that the internal base of both the larger and smaller pipes aligns perfectly, preventing any step or lip that could trap debris or cause standing water. Each connection point is equipped with factory-fitted captive seal rings, providing an immediate, watertight, and root-resistant seal right out of the box. This user-friendly push-fit configuration eliminates the need for specialist welding, allowing installers to transition between pipe sizes quickly and efficiently on site.
 
The smooth internal transitions maintain optimal hydraulic flow, minimizing turbulence and reducing the risk of sediment accumulation across the size change. Whether you are stepping down a main drainage run or connecting a 110mm branch line into a larger 160mm trunk sewer, this level invert reducer delivers professional-grade accuracy, durability, and hydraulic efficiency.
