Starflange® – Series 3200

Restrained Adapter Flange Coupling for Ductile Iron Pipe - Sizes 3" - 36"

StarFlange

Information

StarFlange™ Series 3200 is a restrained adapter flange coupling device designed to connect plain end ductile iron pipe to a flanged pipe, valve or fitting. A ductile iron flange body provides the flange connection and includes an O-ring gasket that seals with the mating flange. The Stargrip® Series 3000 provides restraint for the plain end ductile iron pipe. StarFlangeTM Series 3200 pressure ratings listed on the next page are based on use with PC 350 or TC 50 (or above) ductile iron pipe.
