Macro HP Two-Bolt Extended Range Coupling
Brand: Romac Industries, IncDesigned for Strength and Long Life
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 & NSF 61 certified. End rings are E-coated epoxy.
High Performance Gaskets
With a single gasket Macro couplings accommodate IPS through cast iron pipe.
XL sizes cover DI through Oversize Cast Iron.
For larger pipe diameters such as some asbestos cement, a separate A/C gasket is included.
Easy to Handle and Install
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 inch).
If your work space requires it, the end rings can be clocked.
The Macro is lighter than traditional wide range couplings.
Segmented End Rings
Segmented end rings compress the gaskets evenly around the entire pipe diameter.
The integrated hinge allows the Macro to be easily disassembled if necessary.
Cathodic Protection
The Macro can be ordered with an adapter/connection for cathodic protection if desired.
Allows Deflection
When properly installed the Macro HP can accommodate pipe deflection of up to 10 degrees on sizes 2"-12" (5 degrees each end), and up to 8 degrees on 16" (4 degrees each end).
