Ermetic drain connectors are used to connect roof membranes with rainwater drains. The slightly conical-shaped tang facilitates installation in rainwater pipes. The elastic material from which they are produced guarantees a long-lasting seal. Knurling at the top of the tang ensures a perfect attachment of the Leaf-Excluders and Gravel-Excluder to the drain connector. They have excellent resistance to deterioration caused by the sun, ozone and other atmospheric or chemical agents normally present. The elasticity of the raw material from which they are made allows for excellent flexibility even at low temperatures, enabling the mechanical and physical characteristics to remain unchanged for a long time. The completely smooth flange improves the join with the synthetic sheets, while the two rings positioned along the tang guarantee a watertight seal in the event of backflow along the downpipe. The drain connectors are fully compatible with prefabricated PVC synthetic felts. Thorough cleaning of the drain connector and the membrane in the vicinity of the area where it is joined to the drain connector is recommended.
