The Funke BI-Adapter^_® allows you to securely connect pipes that are circular on the inside only
– pipes with a foot (base) or pipes with reinforcement crown, for example – and it also allows you to connect ovoid pipes with circular pipes. The Funke BI-Adapter^® consists of an inner sleeve, an expansion wedge made of 1.4404 stainless steel and an EPDM sealing collar.

Fast, flexible and sealed

The EPDM-covered stainless steel barrel is inserted into the pipe. The user then widens it by driving in the wedge, which press fits it onto the inner wall of the pipe. Several sealing ribs arranged in a ring shape ensure that a tight joint is formed. The VPC^® Pipe Coupling included in the delivery is then mounted and fastened on the other end of the BI-Adapter. This makes it possible to connect a pipe with a circular outer geometry. The outer diameter of the pipe to be connected must be in the clamping range of the VPC^® Pipe Coupling being used. The Funke BI-Adapter® is available for transitions with non-circular external geometry in nominal diameters from DN 150 to DN 1000.
