Eccentric Reducer Coupling 1-1/4

The Anvil 0300153400 eccentric reducer coupling connects pipes of different diameters in drainage systems. It is designed for plumbing professionals and maintenance teams who need a reliable transition between 1-1/4 inch and 1/2 inch threaded pipe ends in cast iron installations.

Threaded Cast Iron Installation

Both ends feature female National Pipe Thread connections for straightforward assembly with standard pipe dope or tape. The cast iron Class 125 body requires careful alignment during tightening to avoid stress on the threads; over-torquing can crack the fitting or strip the coarse iron threads.

Pressure Rating And Schedule 40 Limits

Rated for 175 psi at 150 degrees Fahrenheit, the coupling handles typical residential and light commercial drainage pressures with margin. It is built for Schedule 40 pipe dimensions; using it with thinner or thicker wall schedules may compromise the seal or exceed the pressure rating.

Questions about this item

How can I verify the coupling is seated correctly after installation?

Check that both female threaded ends engage fully on Schedule 40 pipe and that no leakage appears when the system is pressurised up to 175 psi at 150 degrees F.

What components are included and what must be sourced separately?

The box contains the cast iron eccentric reducer coupling only; pipe, thread sealant and any required hangers are not supplied.

Which version should I select for a 1-1/4 inch to 1/2 inch Schedule 40 drain line?

This model 0300153400 is the Class 125 straight coupling with 1-1/4 inch and 1/2 inch female threaded ends, matching that exact reduction.
