Reducing Coupling for Pipe Systems

This galvanized malleable iron reducing coupling joins a 1 inch female NPT thread to a 1/2 inch female NPT thread. It suits plumbing installations that require a step-down in pipe size with a Class 300 pressure rating.

Malleable Iron Build and Threaded Ends

The Class 300 malleable iron body provides mechanical strength for demanding fluid-handling tasks. Both ends use NPT threads with 11 1/2 threads per inch on the larger side and 14 threads per inch on the smaller side for secure engagement.

Pressure Rating and Chemical Notice

Rated for Class 300 service, the fitting handles elevated pressures in standard piping layouts. California Proposition 65 warnings apply because the product contains chemicals identified by the state as causing cancer and birth defects or other reproductive harm.

Questions about this item

What Class 300 pressure rating does this galvanized reducer coupling support?

The coupling is rated Class 300, meaning it handles the working pressures defined for that malleable-iron class in threaded piping systems.

Which thread standards and sizes must the mating pipe and fitting match?

One end uses 1 in female NPT with 11-1/2 threads per inch; the other uses 1/2 in female NPT with 14 threads per inch.

How should the threads be sealed during installation, and what common mistake causes leaks?

Apply PTFE tape or pipe dope on the male threads only, then tighten to the recommended turns-past-hand-tight; skipping sealant or over-tightening the female hub often causes leaks.
