Anvil Malleable Iron Reducer Coupling

The Anvil 0310089800 is a malleable iron reducing coupling rated for Class 150 service. It connects a 2 inch female NPT thread to a 1/2 inch female NPT thread. The fitting is designed for Schedule 40 pipe and carries a maximum operating pressure of 300 psi at 150 degrees Fahrenheit. It is supplied in a black finish.

Plumbers joining dissimilar pipe sizes

This coupling suits installers who need to transition between 2 inch and 1/2 inch NPT threads on Schedule 40 piping systems. It is not intended for tubing, compression or push-fit connections. Buyers who need a straight coupling, a different thread standard or a higher pressure class should look at alternative fittings.

Simple threaded assembly

Installation requires only standard pipe thread sealant or tape applied to the male threads entering each end. The coupling tightens with a pipe wrench on the hex flats. The most common issue is cross-threading or insufficient sealant, which can cause leaks at the joint. Ensure threads are clean and aligned before final tightening.

Questions about this item

What pipe schedules and NPT sizes must my existing piping have to connect this 2 in and 1/2 in reducer coupling?

Both ends are Female NPT, rated for Schedule 40 pipe, with a 2 in inlet and a 1/2 in outlet.

Will the Class 150 malleable iron body handle the same 300 psi at 150 °F limit as my current black iron fittings?

Yes, the coupling is rated for 300 psi maximum operating pressure at 150 °F, matching standard Class 150 service conditions.

After threading the coupling onto both pipes, what visual check confirms a proper seal before pressurising?

Verify that threads are fully engaged on both the 2 in and 1/2 in NPT ends and that the black malleable iron body shows no cracks or gaps.
