Anvil 361157001 Forged Steel Coupling

This Anvil coupling is a forged steel fitting rated Class 3000 for Schedule 160 pipe. It connects two 3 inch female NPT threads in a straight line. The black finish identifies the material and pressure class. It suits industrial plumbing systems that require high-pressure threaded joints.

Sustained pressure performance

Forged construction resists deformation when the system operates continuously at the rated class pressure. Thread engagement remains stable through thermal cycles and vibration. The fitting does not rely on a gasket that can degrade, so leak paths stay sealed under long-term load. It is not intended for welded or flanged pipe assemblies.

Questions about this item

Will the forged-steel coupling generate noticeable heat or noise when installed in a continuously running 3 in NPT line?

The coupling is a static forged-steel fitting with no moving parts, so it produces no operational noise or heat once installed in the pipeline.

What existing pipe and thread specification must I already have for this Class 3000 Schedule 160 coupling to connect properly?

You need 3 in NPT female-threaded pipe ends matching Schedule 160 wall thickness to mate with the coupling's female NPT connections.
