Plumbing Eccentric Reducer Coupling

This cast iron eccentric reducer coupling connects a 2 inch female NPT pipe to a 3/4 inch female NPT pipe. It is designed for Schedule 40 piping systems and rated for Class 125 service. Plumbers and maintenance engineers use it to transition pipe diameters in drainage installations.

Thermal Performance and Pressure Rating

The fitting handles a maximum operating pressure of 175 psi at temperatures up to 150 degrees Fahrenheit. Cast iron construction provides durability under standard plumbing conditions without requiring external power or generating noise during normal fluid flow.

Replaces Worn or Mismatched Drain Fittings

This component upgrades or replaces damaged eccentric reducers in existing drainage networks where a 2 inch to 3/4 inch reduction is specified. The jump is worth it when the current fitting leaks, corrodes, or no longer matches the required pipe schedule and pressure class.

Questions about this item

How do I install the 2 in x 3/4 in cast iron eccentric reducer coupling and what step is often missed?

Thread the NPT ends onto Schedule 40 pipe using pipe sealant; the step often missed is aligning the eccentric offset so the reducer drains completely without trapping air.

What maintenance or replacement will the Anvil 0300155009 coupling need over time?

Inspect threads and the cast iron body periodically for corrosion or cracking; replace the coupling if leaks appear at the NPT joints or if the Class 125 rating is exceeded.

What is the first limit reached under sustained use at the 175 psi rating?

The 175 psi maximum operating pressure at 150 degrees F is the primary limit; sustained exposure near this pressure and temperature can accelerate seal degradation and casting stress.
