3" Ductile Iron Extended Range 2-Bolt Coupling | ROMMACROHP3

Key Features

• Ductile iron end rings and center ring have no welds, heavy-duty stainless steel bolts with anti-galling protection, 304 stainless steel armors are bonded to the gaskets, center ring is fusion bonded epoxy in accordance with AWWA C213 and NSF 61 certified, end rings are e-coated epoxy
• With a single gasket macro couplings accommodate IPS through cast iron pipe, XL sizes cover ductile iron through oversize cast iron, for larger pipe diameters such as some asbestos cement, a separate A/C gasket is included
• The built-in handle makes the macro simple to carry and maneuver during installation, stab fit installation, each end of the macro tightens independently with a single bolt (two bolts each end for 16 in.), if your work space requires it, the end rings can be clocked, the macro is lighter than traditional wide range couplings
• Segmented end rings compress the gaskets evenly around the entire pipe diameter, the integrated hinge allows the macro to be easily disassembled if necessary
• The macro can be ordered with an adapter/connection for cathodic protection if desired
• All cast components (end rings, center ring and bolt guides) are ductile iron, meeting or exceeding the requirements of ASTM A 536,-grade 65-45-12
• 4 to 12 in. end rings are segmented and joined with an integrated hinge, 2 in. and 3 in. use a type 316 stainless steel pin, the gap is spanned by the armor, 16 in. macro end rings consists of two halves connected with bolts
• Cast with integral handle for ease of assembly
• Made from virgin Ethylene Propylene Diene Monomer Rubber (EPDM) compounded for water and sewer service in accordance with ASTM D2000, NSF 61 certified
• Heavy gauge 304 stainless steel
• Type 304 stainless steel, 2 in. and 3 in. are 1/2-13 UNC, 4 to 16 in. are 5/8-11 UNC, all are carriage head bolts with heavy hex nuts, fasteners provided with anti-galling protection
• Center ring fusion bonded epoxy in accordance with AWWA C213 and NSF 61 certified, end rings E-coated epoxy
