This top hat pipe connector, or pipe connection plate, is for connecting inlet, outlet and vent pipes through the membrane liners of attenuation and soakaway crate systems.
Top hats are installed by using 50mm double-sided butyl tape between the top hat and membrane and 75mm PVC tape around the perimeter of the top hat.
This top hat connects to ULTRA3 drainage pipework and fittings, or other smooth wall PVC pipework (EN 1401-1 / EN 13476-2).
