The transition from a diameter of 200 mm to 140 mm in a short design is provided by this PVC-U fitting, which is designed for large-scale piping systems requiring the PN16 class.
The close diameter ratio of 200/140 mm is suitable for installations where only a slight narrowing of the flow cross-section is required without a significant increase in flow velocity.
Gluing as an assembly technique is particularly advantageous in this dimension, as the resulting joint has strength comparable to the pipe itself and requires no screws, flanges or seals.
