Malleable Iron Reducer Coupling Class 150

This Anvil 0310086400 coupling connects pipes of different diameters in plumbing systems. It features a malleable iron construction rated for Class 150 service. The fitting joins a 3/4 inch female NPT thread to a 1/4 inch female NPT thread. It suits installers needing a durable reducing joint for Schedule 40 pipe.

Thermals noise and power draw in normal use

As a passive pipe fitting, this component generates no operational noise and draws zero power. It withstands a maximum operating pressure of 300 psi at temperatures up to 150 degrees Fahrenheit. The malleable iron body handles thermal cycling within this range without active cooling. No electrical or thermal management is required.

Questions about this item

How do I install the Anvil 0310086400 reducer coupling on Schedule 40 pipe, and what step is often missed?

Apply thread sealant to the 3/4 in and 1/4 in NPT female threads, tighten to the fitting, then pressure-test at up to 300 psi; the step often missed is confirming full thread engagement before pressurising.

What maintenance or replacement will the malleable iron Class 150 coupling need over time?

Inspect threads and sealing surfaces periodically for corrosion or leakage; replace the coupling if thread damage or body cracks appear, as malleable iron cannot be repaired once compromised.
