Ductile iron fittings for pressurised plastic pipes

IZIFIT is a comprehensive ductile iron fittings solution for all types of plastic pipelines used in the distribution of drinking water and is the cornerstone of all PVC networks.

For good mechanical resistance, ductile iron fittings have to be used with all plastic tubes made of PE (Polyethylene), PVC­U (Unplasticized Polyvinyl Chloride), and PVC­BO (Biaxially Oriented Polyvinyl Chloride).  

The versatile fittings include bends, tees, flange spigots, flange sockets, tapers, stoppers, semi­sliding collars, and anchoring sleeves used to connect two plastic networks. Addressing several applications and markets, IZIFIT can also be used to connect two different networks, for example, one in BLUTOP ductile iron and another in plastic (PE).


Easy installation: as a unique technology developed and patented by Saint-Gobain PAM, the IZIFIT solution accelerates and simplifies the installation of joints while guaranteeing watertightness. With pre-fitted gaskets and handles for carrying, the fittings and gate valves are ready to be installed and can be easily assembled by hand or simple leverage without any tightening.

Resistance: the IZIFIT range offers the possibility of anchoring the pipe or not (watertight joint or anchoring joint). The fittings offer resistance, durability and flexibility as demonstrated by their pressure resistance of up to PFA 16 bar (depending on the plastics used). Their blue epoxy coating and inserts in stainless steel and EPDM quality elastomer further ensure excellent resistance to the test of time.

Stability: the angular deflection supported by IZIFIT fittings is 6°, regardless of the joint used. The axial withdrawal tolerated by the joints means the pipeline can accommodate ground movement.

High standards: the joints are designed and tested according to rigorous methods and standards (NF T 54­948-2010 for PVC­BO and EN 12842­2012 for PE and PVC­U), while our company-specific tests provide unrivalled reliability.
