PVC Collars H 250-400

The collars h 240-400 have the function of connecting the mantles with any through pipes. They have a large flange for optimal bonding with prefabricated membranes. 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 tang has a slightly conical shape to make installation easier. The elastic material they are made of ensures long-term water tightness. They provide excellent resilience to deterioration caused by the sun, ozone and other weather agents or chemicals normally found in the atmosphere.

They are perfectly compatible with PVC prefabricated synthetic membranes. We recommend thoroughly cleaning the collar and synthetic felt near the area where the collar will be joined.
