EPDM Ermetic drain connectors H 240

EPDM Ermetic drain connectors perform the function of connecting roofing membranes with rainwater drains. The slightly conical shape of the tang allows for fast and simple installation in rainwater drain pipes.  The elastic material they are made of ensures long-term water tightness. The top part of the tang has a series of serrations that ensure the leaf-excluder or gravel-excluder is firmly attached to the drain connector.

They provide excellent resilience to deterioration caused by the sun, ozone and other weather agents or chemicals normally found in the atmosphere. The elasticity of the material allows an excellent flexibility even at low temperatures, which ensures mechanical and physical properties are maintained over time.

The completely smooth flange promotes bonding with the synthetic sheet, while the two rings along the tang guarantee an airtight seal against backflow in the event of water rising up along the downpipe.
The drain connectors is perfectly compatible with prefabricated EPDM synthetic sheets.
Careful cleaning of the connector and the synthetic felt in the vicinity of the area joining to the connector is recommended.
