Eccentric Reducer Coupling for Drain Systems

The Anvil 0300154606 is a cast-iron eccentric reducer coupling designed for drain and trap installations. It connects a 2-inch female NPT pipe to a 1-1/4-inch female NPT pipe. This fitting suits plumbers and maintenance crews joining dissimilar pipe sizes in gravity-flow systems.

Class 125 Rating Handles Standard Pressure

Rated at 175 psi at 150 degrees F, the coupling meets Class 125 specifications for Schedule 40 piping. Cast-iron construction resists corrosion and vibration in normal drain service. The eccentric profile keeps the bottom of the pipe run level to prevent air pockets.

Sustained Service Within Rated Limits

Under continuous operating pressure up to 175 psi and temperatures up to 150 degrees F, the fitting maintains its seal without deformation. The rigid cast-iron body does not relax or creep over time. It is not intended for pressures or temperatures beyond the stated Class 125 limits.

Questions about this item

How do I install the 2" x 1-1/4" FNPT eccentric reducer coupling and what step is often missed?

Clean both pipe threads thoroughly, apply PTFE tape or pipe dope to the male threads only, then tighten the coupling onto the 2" and 1-1/4" pipes using two wrenches to prevent stress on the cast iron body; the step often missed is using a second wrench to back up the fitting.

What maintenance or replacement will the cast iron Class 125 coupling need over time?

Inspect the joint annually for rust, seepage or white mineral deposits; if the cast iron body cracks or the threads strip, replace the entire 0300154606 coupling — no internal serviceable parts exist.

At what pressure and temperature limit does the Schedule 40 coupling reach its maximum rating during sustained use?

The coupling is rated for 175 psi at 150 °F; sustained operation above either limit will cause the cast iron Class 125 body to fail first.
