Telescopic connection DN 160, main pipe wall thickness 180 to 270mm (1 resin box included) FTA160270SET

It allows to make connections to masonry ducts and collectors, concrete collectors or collectors made of vibrated concrete with all generally available profiles and wall thicknesses from 180 to 560 mm.
The lower part of the telescopic coupling consists of a 48 cm long plastic tube with an elastic sealing ring in the lower part. The upper part of the joint is a combination of a VARIO-socket, a plastic sealing flange and two blue and white wires through which the expansion resins are supplied. The movable VARIO ball joint, which can be set at an angle of 0 to 11 degrees, offers greater flexibility when connecting house connections.
Good seating of the joint is guaranteed by cast resin, which fills the empty space between the structural element and the wall of the collector or
