CouplingsSECTION 1: COUPLINGSRigid Coupling Systems and Performance §Zero-Flex Style 07, Style 606 Copper, and transitionStyle 307 rigid couplings have a unique, patented angledpad design which constricts the housing keys into thegroove around the full circumference to create a rigidjoint. The housings slide on the angled pads ratherthan mating squarely.This sliding movement also forces the key sections intoopposed contact on the inside and the outside grooveedges, which locks the coupling onto the pipe endsand creates a rigid connection.These rigid couplings provide a rigid joint allowingno expansion/contraction or linear movement.The couplings will position the pipe ends so that thereis a fixed pipe end separation that may be consideredduring design and installation (see chart below).Rigid couplings (Styles 07, W07, 606, 89, 489, 307,HP-70, 741 and others) create a rigid joint, usefulfor risers, mechanical rooms and other areas whereflexibility is not desired. Zero-Flex Style 07 and StyleW07 AGS couplings are designed to provide rigidityto permit hanging to ASME B31.1 Power Piping Code,ASME B31.9 Building Services Piping Code andNFPA 13 Sprinkler Systems.SizeAllow.
