Tpe Collar - Smooth Flange

H 250 - 400 Smooth Flange

TPE COLLARS are used to connect the waterproof bituminous felts to any through tubes or systems on the roofing. They have a large smooth flange for excellent adhesion with bituminous sheaths.

The h 250 models can be easily cut by following the marked lines and bringing the outfeed diameter to 20, 25 or 30 mm for Ø 18 and to 30, 35 or 40 mm for Ø 28. h 400 models are instead available in four different diameters and the shank has a slightly conical shape to make installation easier.

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 APP and SBS prefabricated bituminous membranes and bituminous coats. A sandwich installation between the two layers of membrane is recommended to achieve top performance. To improve adhesion, a thin coat of primer can be applied on the drain connectors beforehand.
