EPDM Siphoned drain connectors H 250

The EPDM siphoned drain connectors are used to connect waterproof bituminous felts to rainwater drains and with the special siphon, they stop unpleasant odours from the drains. The slightly conical shape of the tang allows for fast and simple installation in rainwater drain pipes.

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 for excellent flexibility even at low temperatures, which ensures mechanical and physical properties are maintained over time.

The perforated flange favours adhesion with bituminous sheaths, while a number of rings along the tang ensure an anti-surge airtight seal in the event of water rising along the downpipe.
The connector is 100% compatible with APP and SBS prefabricated bituminous membranes and bituminous coats. For maximum performance, sandwich laying between two membrane layers.
To improve adhesion, the connector can be pre-coated with a light coat of primer.
Along with the siphon, the drain drain connectors comes with a special leaf-/gravel-excluder cage.
