The AVK Supa MaxiTM couplings are designed with a sealing support system that provides full support to the gasket and full tensile strength on all pipe types up to PN16. This is possible through the use of two different metal grip segments every other of gunmetal for PE/PVC and of hardened stainless steel for cast iron/ductile iron/steel/stainless steel/GRP/asbestos cement pipes. For PE pipes a support bush is to be used.
