Anvil Black Forged Steel Reducer

This Anvil black forged steel reducer connects 1 1/2 inch FNPT pipe to 1 inch FNPT pipe in Class 3000 piping systems. It meets ASME B16.11 and ASTM A106 standards for high-pressure service. The fitting suits industrial steam, water, oil, and gas lines requiring a durable, pressure-rated transition.

Suitable Installations and Limitations

This coupling fits installers joining dissimilar pipe sizes with female NPT threads under Class 3000 ratings. It serves systems operating up to 1500 psi at 150 degrees F or 300 psi saturated steam at 550 degrees F. Buyers needing welded connections, different thread standards, or larger diameter transitions must select alternative fittings.

Class 3000 Pressure Rating Decides Fit

The Class 3000 designation defines the fitting's pressure boundary at 1500 psi maximum at 150 degrees F. This single rating determines whether the reducer matches the piping system's design pressure and temperature requirements. Verify the system class against this value before installation.

Questions about this item

What pipe sizes does the 1 1/2 in x 1 in FNPT reducer connect?

The coupling joins a 1 1/2 inch female NPT pipe to a 1 inch female NPT pipe using forged steel threads.

How do I seal the FNPT threads during installation without cracking the Class 3000 fitting?

Apply PTFE tape or pipe dope to the male threads only, then tighten two turns past hand-tight; over-torquing splits the forged steel body.

When should I replace the reducer if it sees saturated steam at 300 psi and 550 Degrees F?

Inspect yearly for thread erosion or body cracks; replace immediately if steam leaks appear or the fitting exceeds its 550 Degrees F temperature limit.
