DEKS Waga GF3107-150-100 reducing coupling is a reliable restraint connection for all types of pipe materials including DI, AC, CI, PE, PVC and steel pipe. The MULTI/JOINT 3000 Plus wide range system meets all demands and is suitable for applications in water for pipe sizes from 154-192 x 104-132mm OD. The design of the socket consists of a segmented thermoplastic ring combined with a thin gasket, embedded with 316 S/S metal grippers (Uni/Fiksers). Sealing is accomplished by tightening a number of 316 S/S metal nuts and bolts to engage the ductile iron clamp ring onto the socket. The angular deflection is ± 8 o per socket end. For restraint versions on P.E and P.V.C pipes, the use of an insert stiffener (see accessories) is mandatory.
