  • Suitable for Schedule 40 piping systems
  • Black finish protects against corrosion

Reducer Coupling for Schedule 40 Pipe

The Anvil 0310088802 is a malleable iron reducing coupling rated Class 150. It connects 1 1/2 inch female NPT pipe to 1/2 inch female NPT pipe. The fitting is designed for use with Schedule 40 piping systems in plumbing installations. It suits professionals and DIYers needing a durable transition between different pipe diameters.

Pressure and Temperature Performance

The coupling handles a maximum operating pressure of 300 psi at 150 degrees Fahrenheit. Malleable iron construction provides mechanical strength under normal service conditions. The black finish is standard for this class of fitting. No noise or thermal expansion data is provided by the manufacturer.

Single Critical Specification

This reducer coupling joins 1 1/2 inch and 1/2 inch female NPT threads only. It will not fit other thread sizes, pipe schedules or connection types. Buyers needing different diameters, male threads or a higher pressure class must select another fitting.

Questions about this item

How do I install the Anvil 0310088802 reducer coupling without damaging the NPT threads?

Wrap the 1 1/2 in and 1/2 in female NPT threads with PTFE tape or pipe dope, then hand-tighten before using a wrench for one to two turns; over-tightening cracks the malleable iron.

What maintenance will the Class 150 malleable iron coupling need over time?

Inspect the black finish annually for rust or scale; re-apply thread sealant if a joint weeps, and replace the coupling if corrosion reduces wall thickness below Schedule 40 requirements.

At what pressure does the 300 psi rating limit sustained use at 150 Degrees F?

The coupling is rated for 300 psi maximum operating pressure at 150 Degrees F; sustained pressure above this limit risks permanent deformation of the Class 150 malleable iron body.
