Smith-blair 461-12751440-000 Quantum Coupling 12 Inches Ductile Iron Flexi-coat Fusion Bonded Epoxy

Product Description

The Smith-Blair 461-12751440-000 Quantum Coupling is a 12-inch ductile iron pipe coupling engineered for waterworks, municipal, and industrial piping systems. It is part of the Smith-Blair Series 461 Quantum Coupling line, manufactured by Xylem, a trusted name in fluid management infrastructure. This coupling is designed to join pipe sections quickly and reliably, making it a go-to solution for water distribution, wastewater, and industrial pipeline repair or new installation work. The casting method used in its manufacture ensures consistent wall thickness and structural integrity under demanding field conditions. The Flexi-Coat Fusion Bonded Epoxy finish provides corrosion protection both inside and out, extending service life in buried, submerged, or exposed environments. This coupling accommodates an outside diameter range of 12.75 to 14.4 inches, giving installers flexibility when working with varying pipe tolerances, including cast iron, ductile iron, steel, and certain plastic pipes within that OD range. The temperature rating of -20 to 180 degrees Fahrenheit makes it suitable for cold-climate installations as well as moderately heated fluid applications. The Quantum design philosophy centers on a streamlined component system with fewer parts than traditional couplings. This reduces the inventory a contractor or utility must carry on hand and simplifies handling on the job site. Lighter weight compared to older cast iron designs means easier handling in trenches and tight spaces. Faster installation translates directly to lower labor costs on repair jobs and new construction alike. Plumbers, pipefitters, and waterworks contractors working on 12-inch main lines will find this coupling a practical, field-proven choice for both emergency repairs and planned connections.

• Ductile iron construction with Flexi-Coat Fusion Bonded Epoxy for corrosion resistance inside and out
• Fits outside diameters from 12.75 to 14.4 inches for compatibility with multiple pipe materials and sizes
• Temperature rated from -20 to 180 degrees Fahrenheit for broad installation suitability

Product Highlights

The Smith-Blair 461-12751440-000 Quantum Coupling delivers a durable, corrosion-resistant connection for 12-inch pipelines with a simplified design that reduces parts count and speeds up installation. Its wide OD range and epoxy coating make it well suited for waterworks, municipal, and industrial piping applications.
