Product Introduction

Ductile Iron Grooved Couplings are fittings used to join and connect grooved pipes in a wide variety of piping systems. These couplings are made of high-quality cast iron material for excellent strength and durability and typically meet ASTM A536 Grade 65-45-12 standards. They are available in a variety of types, including flexible and rigid couplings, for different applications.

The working pressure of these couplings varies by size and type; for example, 2-inch couplings can withstand pressures up to 500 PSI (3.45 MPa), while 6-inch couplings are typically in the 300 PSI (2.07 MPa) range. (250mm) or larger, and are suitable for a variety of applications such as fire protection, HVAC systems, industrial piping, and water supply and distribution.

These couplings are easy to install, provide a reliable seal, are corrosion-resistant, and are often coated with epoxy for added corrosion resistance. They are compatible for use with a variety of grooved fittings such as elbows, tees, reducers, and more. When selecting Ductile Iron Grooved Couplings, consider the working pressure, pipe size, and specific certifications required to ensure that they meet the standards and specifications for your particular piping system.
