TPO COLLARS are used to connect waterproof bituminous felts to any through tubes or systems on the roofing.
The slightly conical shape of the shank makes it easier to install through tubes and the smooth flange for excellent welding to TPO synthetic felts.
The elastic material they are made with ensures long-term watertightness. 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 synthetic felts. We recommend thoroughly cleaning the collar and felt near the area where the connector will be welded.
