Anvil 311089601 Reducer Coupling

This Anvil galvanized reducing coupling connects a 2 inch female NPT pipe to a 3/4 inch female NPT pipe. It is made from malleable iron with a Class 150 rating for Schedule 40 piping systems. The fitting suits plumbing and hydraulic circuits that require a step-down in pipe size.

Installation uses standard NPT threads

Both ends have female NPT threads so the coupling threads onto male pipe ends with thread sealant or tape. The galvanized coating resists corrosion during assembly but can flake if overtightened; use a pipe wrench on the fitting flats only. Malleable iron is brittle compared with steel, so avoid excessive force that could crack the body.

Rated for 300 psi at 150 °F sustained

The Class 150 design handles a maximum operating pressure of 300 psi at temperatures up to 150 degrees Fahrenheit. Under continuous pressure and heat the galvanized layer remains stable and the joint maintains its seal. The coupling is not rated for higher pressures or temperatures beyond the stated limits.

Questions about this item

How can I confirm the 300 psi Class 150 reducer coupling is sealed correctly after threading it onto Schedule 40 pipe?

Pressurise the system up to the 300 psi rating at ambient temperature and inspect both 2 in and 3/4 in FNPT joints for leaks; a dry, bubble-free joint confirms the galvanized malleable iron fitting is working as intended.

What comes with the Anvil 311089601 reducer coupling and what must I supply?

The box contains only the 2 in x 3/4 in FNPT galvanized reducing coupling; you must provide Schedule 40 pipe, NPT thread sealant or tape, and appropriate wrenches for installation.

Which version of the Anvil 311089601 should I choose for a 300 psi water line?

Select the listed 2 in x 3/4 in FNPT Class 150 galvanized malleable iron reducer; it is rated for 300 psi at 150 °F and matches Schedule 40 piping requirements.
