Style 461 | Quantum Coupling | Alloy Coated

Typically ships in 7-10 business days

Made to Order – Nonreturnable

Product Features:

• Wide Range Cast Couplings 
• Application Joining plain end pipe of all outside diameters within the coupling range.  
• Great for reducing coupling inventory 
• Heavy cast Ductile Iron parts for long life 
• Meets applicable AWWA C219 Standards 
• Stab fit making installation a breeze. No disassembly required 
• Bolts and nuts are coated for superior corrosion resistance and better torque capabilities Up to 1.65 of range with a single gasket and flange reducing the need for large coupling inventories 
• One coupling per nominal pipe size takes the guesswork out of deciding which coupling size to choose
