KAN-therm Push fittings have specially profiled connectors, thanks to which the construction needs no additional seals. An expanded end is inserted on the connector and then pressed to the surface of the fitting with a sliding sleeve. The pipe is clamped circumferentially on the coupling stub in the entire contact plane.
Such a connection allows for conducting the installation in structural partitions (in flooring finishing coats and under layers of plaster) without any limitations.
Connections without O-rings have been working seamlessly in projects for over 30 years now - it is one of the safest and most reliable technologies for installing plastic pipes.
