Manufactured of a special compound of thermoplastic rubber, it is highly resistant against low temperatures (cold flexibility = -40°) as well as perfectly compatible with all sorts of bituminous waterproofing membrane. The traditional dove-tail channels and special shagreens on the flange allow a perfect bond to the membrane. The spigot is provided with two or three couples of anti-infiltration tongues that prevent any infiltration between the spigot and the drain pipe.
