Building entry Lu-SW

Building entry Lu-SW (DN 80/100) against pressing water


Our Lu-SW building entry consisting of a compact EPDM elastomer ring and flexible segmental pressure plates will save you a lot of time and effort due to its split and custom-fit construction. It can be easily installed subsequent to the installation of the carrier pipe by simply opening the seal insert, putting it around the carrier pipe, inserting it into the core-drilled hole or the wall sleeve, and tightening it. It is not necessary to dismantle the carrier pipe beforehand.

The pressure plates are furnished with a surrounding wedged rim which is forced into the elastomer ring when tightening the screws. This will transfer the starting power directly to the seal ring and prevent the rubber from oozing out at the sides or from under the pressure elements. The pipe penetration can be equipped with connecting elements made of galvanized or stainless steel on request.
