Anvil 2 in to 1 1/2 in Cast Iron Eccentric Reducer

This Anvil eccentric reducer coupling joins a 2 in NPT female pipe to a 1 1/2 in NPT female pipe. It is made from cast iron and rated Class 125 for Schedule 40 piping systems. The fitting suits plumbing and drainage installations that require a change in pipe diameter while maintaining a straight bottom line.

Installation uses standard NPT threads on both ends

Thread sealant or tape is applied to the male threads before tightening into the female ports. The eccentric design keeps the bottom of the pipe run level, which helps drainage flow. Over-tightening can crack the cast iron body, so hand-tight plus one to two turns with a wrench is typical practice.

Class 125 pressure rating defines the operating

The coupling withstands 175 psi at 150 degrees F maximum operating pressure. Systems that exceed this pressure or temperature need a higher-class fitting. Buyers who need a straight reducer or a different pressure class should select another part.

Questions about this item

How can I confirm the Anvil 0300154408 coupling is sealed correctly after threading it onto the pipe?

Pressurise the line up to 175 psi at no more than 150 °F and check both NPT joints for leaks; a dry, drip-free connection shows the Class 125 casting and Schedule 40 fit are working as intended.

What comes with the Anvil 0300154408 reducer and what extra items are needed for installation?

The box contains only the black cast-iron eccentric reducer coupling with 2 in and 1 1/2 in female NPT threads; you must supply pipe-thread sealant or tape and the Schedule 40 pipes that match those thread sizes.

Which version of the Anvil 0300154408 should I choose for a standard drainage line?

This single model is a Class 125 eccentric reducer coupling rated 175 psi at 150 °F for Schedule 40 pipe, so select it when you need to step from 2 in NPT down to 1 1/2 in NPT in a drainage system.
