Anvil 2" x 3/4" Reducer Coupling

The Anvil 0310089602 is a straight malleable iron fitting designed to join a 2-inch female threaded pipe to a 3/4-inch female threaded pipe. It serves plumbers and maintenance technicians who need a durable transition between dissimilar pipe diameters in water, air, or oil lines. Class 150 construction suits standard Schedule 40 piping systems.

Verify Threads, Schedule, and Pressure

Confirm that both existing pipe ends carry female National Pipe Thread (FNPT) connections and match Schedule 40 dimensions before ordering. The coupling is rated for a maximum operating pressure of 300 psi at 150 degrees Fahrenheit, so ensure the system design stays within that limit. No other pipe schedules or thread types are compatible with this fitting.

Malleable Iron Build and Daily Use

The Class 150 malleable iron body resists mechanical shock and vibration better than cast iron, giving reliable service in industrial and commercial installations. Female threads on both ends allow direct engagement with male-threaded pipe nipples or valves without extra adapters. The straight pattern keeps flow restriction low while the iron construction handles thermal cycling in heated fluid circuits.

Questions about this item

What does the Anvil 0310089602 reducer coupling include and is any sealant or tape required?

The box contains the single malleable iron coupling with female NPT threads on both ends. Thread sealant or PTFE tape must be purchased separately to make a leak-free joint.

How do I choose between the 2 in and 3/4 in ends on this Class 150 Schedule 40 fitting?

The 2 in female thread connects to the larger pipe or drain line; the 3/4 in female thread accepts the smaller branch pipe. Select this coupling only when you need to step down from a 2 in line to a 3/4 in line.

What does the 300 psi at 150 °F rating mean when the coupling is installed in a hot-water system?

It indicates the maximum continuous pressure the Class 150 malleable iron body can safely hold at 150 °F. At lower temperatures the same 300 psi limit applies; do not exceed it in service.
