Value Brand 2" Malleable Iron Coupling

2-Inch Malleable Iron Coupling

This coupling joins two sections of 2-inch pipe using female National Pipe Thread connections. It is built from malleable iron rated to Class 300 for demanding plumbing and industrial piping systems. The fitting meets ASME B16.3, ASME B16.4, ASTM A47 and ASTM A197 standards and carries FM Approved and UL Listed markings. It is suited for installers who need a durable, code-compliant joint.

Class 300 FNPT Connection

The female threaded ends accept matching male NPT pipe or nipples without welding or flanges. Malleable iron construction tolerates mechanical stress and vibration better than cast iron in the same class. The coupling frees the installer from aligning bolt-hole patterns or managing gasket surfaces required by flanged alternatives. It fits any system designed around 2-inch NPT threads and Class 300 pressure ratings.

1500 psi at 150 Degrees F Rating

Under sustained pressure the coupling holds up to 1500 psi at 150 degrees Fahrenheit and 300 psi for saturated steam service. The material remains rated across a continuous temperature range from minus 20 to 550 degrees Fahrenheit. These limits apply to steady-state conditions rather than momentary spikes. Systems operating beyond these pressure or temperature boundaries require a higher-class fitting.
