Anvil Eccentric Reducer Coupling

This Anvil eccentric reducer coupling connects a 1 inch female threaded pipe to a 1/2 inch female threaded pipe. It is built from cast iron for drainage and trap installations. The fitting meets Class 125 specifications and suits Schedule 40 piping systems. Plumbers and maintenance crews use it to transition pipe sizes in straight runs.

Upgrade from mismatched bushings

Replacing a reducing bushing with this eccentric coupling keeps the pipe invert level, preventing air traps in horizontal drainage lines. The jump is worth it when a straight size change is required without altering the flow line elevation. It handles a maximum operating pressure of 175 psi at 150 degrees Fahrenheit.

Simple threaded installation

The coupling installs by threading each end onto the corresponding pipe using standard pipe sealant or tape. Cast iron threads can be brittle, so over‑tightening often cracks the fitting. Ensure the pipes are aligned to avoid stress on the joint during assembly.

Questions about this item

What thread sizes does the 1 in x 1/2 in eccentric reducer coupling use?

It has a 1 in female threaded end and a 1/2 in female threaded end, both straight threads for Schedule 40 pipe.

Which sealant works on the cast iron threads during installation?

Use PTFE tape or pipe dope rated for 175 psi at 150 °F; tighten until snug, then one extra turn — over-tightening cracks the Class 125 casting.

How often should the coupling be inspected for corrosion or leaks?

Check joints annually; replace if white rust appears on the cast iron or if seepage occurs at the 175 psi rating.
