This adaptor coupling is used for connecting clay pipes to twin wall plastic pipes with differing external diameters, specifically 160–170mm to 170–192mm. It is commonly applied in drainage and sewer installations where joining old and new pipe systems is necessary.
The coupling creates a secure, sealed joint between pipes of varying sizes, helping to maintain system integrity and prevent leaks. It is often utilised for pipe connections to manholes, inspection chambers, or where lateral inlets are required on site.
