For TPO Felts
The TPO ERMETIC DRAIN CONNECTORS are used to connect waterproof synthetic TPO felts to rainwater drains. The slightly conical shape of the shank allows for fast and simple installation in rainwater drain pipes.
The smooth flange at the top improves welding to synthetic felts, while the two rings on the shank ensure the product is watertight and does not overflow if any water comes back up the rainwater drain pipe.
The elastic material they are made with ensures long-term watertightness. The top part of the shank 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 for excellent flexibility even at low temperatures, which ensures mechanical and physical properties are maintained over time.
They are 100% compatible with prefabricated TPO felts. We recommend thoroughly cleaning the connector and felt near the area where the connector will be welded.
