This 160mm to 110mm level invert reducer is designed to reduce pipe diameter while keeping the invert (the internal bottom of the pipe) aligned. Maintaining a level invert helps support consistent flow characteristics and reduces the chance of settlement points where debris can collect.
Manufactured from durable PVCu, it’s built for underground gravity drainage environments. The tapered profile provides a smooth transition between sizes, while the single socket connection supports straightforward installation using compatible seals within standard drainage systems.
