Tough, durable and flexible drain connector, used for downpipes and circular outlets on a roof or terrace within the main body of a concrete deck. It is suitable with synthetic membranes.

The shank is inserted into a hole to connect to the outlet drainage pipe and the flange is welded to the membrane. The flange is not perforated.

Bonded by using hot air gun (not direct contact to a flame).

The pipe is manufactured in a slight cone shape to give easy installation and to prevent it from rising out of the hole. There are also two rings on the exterior of the pipe, which help to ensure that no water can travel back up and ensure a tight fit. The drain connectors are designed to sit inside an HDPE outlet pipe with a snug fit and a range of size options are available in relation to the relevant outlet pipe size.
