1" Malleable Iron Coupling for Schedule 40 Pipe

This coupling connects two sections of 1-inch Schedule 40 pipe using female NPT threads on both ends. It is made from malleable iron rated to Class 150 for standard plumbing and drain installations. The fitting suits installers who need a durable, threaded joint in residential or light commercial systems. It does not suit applications requiring compression, push-fit or flanged connections.

Rated 300 psi at 150 °F Maximum Operating Pressure

The Class 150 malleable iron body handles up to 300 psi at 150 degrees Fahrenheit in normal service. No moving parts or seals mean there is no mechanical noise and no power draw associated with the fitting itself. Thermal expansion follows the base metal characteristics under typical hot-water or steam conditions. The fitting contains no electrical or electronic components.

Supplied as a Single Threaded Fitting

The box contains only the coupling; no gaskets, thread sealant, tape or installation tools are included. Installers must provide compatible pipe sealant or PTFE tape rated for the system pressure and temperature. No software, firmware or digital configuration is involved. The product ships as a standalone hardware component for immediate assembly.

Questions about this item

How do I install this 1" FNPT malleable iron coupling on Schedule 40 pipe, and what step is often missed?

Clean threads, apply pipe thread sealant or tape, thread the coupling onto each pipe end by hand, then tighten with a pipe wrench; the step often missed is using the correct sealant for NPT threads to prevent leaks at the 300 psi rating.

What maintenance or replacement will this Class 150 coupling need over time?

Inspect periodically for corrosion, cracking, or thread damage; replace if leaks appear or if the malleable iron shows signs of degradation from fluid exposure or thermal cycling at 150 °F.

What is the first limit reached under sustained use at the rated 300 psi and 150 °F?

The 300 psi maximum operating pressure at 150 °F is the primary limit; sustained operation at or near this pressure and temperature can accelerate material fatigue and seal failure.
