Malleable Iron Reducer Coupling Class 300

This Anvil 0310543202 reducer coupling connects a 1-1/4 inch NPT female pipe to a 1 inch NPT female pipe. It is manufactured from malleable iron and rated for Class 300 service with Schedule 80 pipe dimensions. The fitting handles a maximum operating pressure of 500 psi at 150 degrees Fahrenheit.

Suitable for high-pressure drainage

Installers needing a durable transition between two female NPT threads of different sizes will find this coupling appropriate. It is not for applications requiring a male-threaded connection, a different pressure class, or a material other than malleable iron.

Verify thread standards

Confirm that both pipe ends use NPT threads and that the system design calls for a Class 300 fitting rated to 500 psi at 150 degrees Fahrenheit. Ensure the Schedule 80 wall thickness matches the existing piping specification.

Questions about this item

Do I need Schedule 80 pipe and NPT thread sealant to install the 0310543202 coupling?

Yes, the coupling is rated for Schedule 80 pipe and has 1-1/4 in and 1 in female NPT threads, so matching Schedule 80 pipe and suitable thread sealant are required for a pressure-tight joint.

Will this Class 300 malleable iron reducer couple directly to standard Class 150 fittings I already have?

The coupling is Class 300 rated for 500 psi at 150 °F; connecting it to Class 150 components lowers the assembly rating to the Class 150 limit, so verify your system pressure does not exceed that lower rating.

How can I confirm the 0310543202 reducer is seated and leak-free after assembly?

Pressurise the system up to its design limit, then inspect both NPT joints for drips; a properly made-up joint with sealant will hold 500 psi at 150 °F without visible leakage.
