Anvil Half Coupling 3 in FNPT

The Anvil 361169204 half coupling connects 3-inch pipe with Female National Pipe Taper threads. It is built from straight steel for Class 3000 pressure service and Schedule 160 wall thickness. Plumbers and industrial installers use it to join or extend piping runs in high-pressure systems.

Forged steel construction and threaded seal

The forged steel body resists deformation under normal operating pressure. Threaded FNPT ends create a tight mechanical seal without welding. Black finish protects the surface during storage and installation. No moving parts mean silent operation and zero power draw.

Sustained pressure holding in Class 3000 service

Under continuous load the coupling maintains its pressure rating without leakage. Thread engagement distributes stress evenly across the joint. Schedule 160 wall thickness supports the full Class 3000 design pressure over long periods. The fitting remains stable when system pressure cycles repeatedly.

Questions about this item

How do I install this 3 in FNPT half coupling and what step do people often miss?

Thread the coupling onto the 3 inch pipe using pipe sealant on the FNPT threads; the step often missed is tightening to the correct torque for Schedule 160 wall thickness.

What maintenance or replacement will this Class 3000 forged steel coupling need later?

Inspect threads periodically for corrosion or galling; replace if leaks develop or threads show deformation under pressure.

What limit appears first on this Schedule 160 half coupling under sustained use?

The Class 3000 pressure rating is the limiting factor; sustained pressure above that rating risks joint failure.
