The new Funke VPC^®-Pipe Coupling allows pipes of the same nominal diameters made of different materials to be connected to one another safely, reliably, and with the best possible results – despite having different outer diameters incurred by the design type! The Funke VPC^®-Pipe Coupling consists of a reducible sealing sleeve made of elastomer rubber, a centrically reducible securing cage made of plastic, and two stainless-steel bands for applying force to achieve a uniform circumferential adjustment.
