Elastic sealing membrane for hermetic sealing of openings between pipelines and building structures DN160

Elastic sealing membrane for hermetic sealing of the hole between the pipeline (plastic, cast iron, stainless steel) d 160-165 mm and building structures (outer walls of the basements). Multi-tongue gasket with bitumen collar made of high-quality material and with a plastic safety nut for a firm hold. Easy to put on a smooth end of a pipe or socket, easy to install on uneven surfaces or in the corners of a building (thanks to a special design). Tested for water tightness (up to 6 m water column) - pipe axis deviation is allowed up to 10% from the mounting hole axis.
