2in x 1-1/2in Reducer Coupling

The Anvil 0310544606 is a malleable iron reducing coupling designed for Schedule 80 piping systems. It connects a 2-inch female NPT pipe to a 1-1/2-inch female NPT pipe in drain and trap installations. Plumbers and maintenance engineers specify it for high-pressure fluid transfer where a secure, leak-free reduction is required.

Class 300 Malleable Iron Build

The Class 300 rating supports a maximum operating pressure of 500 psi at 150 degrees Fahrenheit. Malleable iron construction resists cracking under mechanical stress and vibration better than standard cast iron. Female NPT threads on both ends allow direct assembly without adapters, simplifying installation on threaded Schedule 80 pipe.

Upgrade From Standard Class 150 Fittings

This coupling replaces Class 150 fittings when system pressure exceeds their 300 psi limit at the same temperature. The jump is worth it for steam, compressed air or hydraulic lines that regularly see pressures above 300 psi. It is not for systems requiring welded joints or flanged connections instead of threaded NPT ends.
