Cast Iron Reducer for Schedule 40 Pipe

This eccentric reducer coupling connects a 1 inch female NPT pipe to a 3/4 inch female NPT pipe on a drainage system. It is made from cast iron rated for Class 125 service. The fitting handles a maximum operating pressure of 175 psi at 150 degrees Fahrenheit. It is designed for use with Schedule 40 piping.

Suitable for Plumbing Installations

Installers who need to join two different pipe diameters while maintaining a consistent bottom or top level will find this eccentric design appropriate. It is not intended for applications requiring a concentric reducer where the pipe centrelines must stay aligned. Buyers needing a different pressure class or pipe schedule should look elsewhere.

Class 125 Pressure Rating Defines the Limit

The coupling carries a Class 125 rating with a maximum operating pressure of 175 psi at 150 degrees Fahrenheit. This single specification determines whether the fitting meets the pressure and temperature demands of the installation. Verify that the system design stays within these limits before selecting this part.

Questions about this item

What pipe schedules and thread sizes does the 1 in by 3/4 in eccentric reducer coupling accept?

The coupling is rated for Schedule 40 pipe and has 1 inch and 3/4 inch female NPT threads.

Which step is most often missed when threading this cast iron fitting onto pipe?

Apply thread sealant to the male threads and tighten to the recommended torque; skipping the sealant causes leaks.

How often should the coupling be inspected or replaced in a 175 psi steam system?

Inspect annually for corrosion or thread damage; replace if cracking or leakage appears at the 150 °F operating limit.
