Reducing Coupling 1-1/4" x 1/2" FNPT

This Anvil malleable iron reducing coupling connects a 1-1/4 inch female NPT pipe to a 1/2 inch female NPT pipe. It is rated Class 150 for Schedule 40 piping systems. The straight-threaded design suits plumbing installations requiring a secure, leak-resistant joint between dissimilar pipe diameters.

Replaces worn or mismatched threaded fittings

Upgrade when an existing coupling leaks, corrodes or no longer matches the required pipe sizes. The jump is worth it if the current fitting cannot handle 300 psi at 150 degrees F or if the pipe schedule changes to Schedule 40. It is not for systems needing a different pressure class, a non-threaded connection or a material other than malleable iron.

Simple threaded installation with sealant

Apply thread sealant or tape to the male pipe threads before engaging the coupling. Tighten to the recommended turns past hand-tight for the pipe size. What usually goes wrong is cross-threading the female ports, over-tightening which cracks the iron, or using the wrong sealant for the fluid type. Ensure both pipe ends are clean and undamaged.

Questions about this item

What pipe schedule does the 1-1/4" x 1/2" reducing coupling match?

It is rated for Schedule 40 pipe and carries a Class 150 pressure class.

How should the FNPT threads be sealed during installation, and what step is often missed?

Apply PTFE tape or pipe dope on the male threads only, then tighten to the recommended torque; skipping the lubricant causes galling and leaks.

When should the malleable iron coupling be inspected or replaced in service?

Check for corrosion, thread damage or leakage at each system pressure test; replace if the 300 psi rating at 150 °F can no longer be maintained.
