Anvil 1-Inch Class 3000 Half Coupling

This new Anvil half coupling is a forged steel pipe fitting rated for Class 3000 service. It provides a straight, threaded connection for 1-inch nominal pipe built to Schedule 160 dimensions. The fitting is finished in black and uses Female National Pipe Thread (FNPT) on its single connection end. It is designed for industrial plumbing and hydraulic assemblies requiring high-pressure containment.

For Schedule 160 systems needing a 1-inch FNPT joint

This coupling suits installers joining two lengths of 1-inch Schedule 160 pipe where a female threaded connection is specified. It is not for piping built to a different schedule or wall thickness. It is not for applications requiring a male thread, a socket-weld end or a flanged connection. Buyers needing a different nominal pipe size or pressure class should select an alternative fitting.

Rated 2,000 psi at 150 Degrees F

The maximum operating pressure is 2,000 psi at 150 Degrees F. This single pressure-temperature rating determines whether the fitting meets the design conditions of the system. Verify that the service pressure and temperature stay within this limit before installation.

Questions about this item

How do I install the 1" FNPT threads on this half coupling without cross-threading?

Clean both male and female threads, apply PTFE tape or pipe dope to the male threads only, hand-tighten until resistance is felt, then turn one to two full turns with a wrench; over-tightening is the common error that cracks the forged steel.

What maintenance or replacement will this Class 3000 forged steel half coupling need over time?

Inspect threads and sealing surfaces annually for corrosion, galling or deformation; replace the fitting if any leak path appears or if the 2,000 psi at 150 °F rating can no longer be verified.

What is the first limit reached under sustained pressure and temperature with this Schedule 160 fitting?

The 2,000 psi maximum operating pressure at 150 °F is the primary limit; exceeding either pressure or temperature reduces the safety margin of the Class 3000 forged steel body.
