1-Inch FNPT Forged Steel Union

The Anvil 0361530603 is a threaded union designed to join two sections of 1-inch pipe with female National Pipe Taper threads. It is built for plumbing professionals and industrial maintenance teams who need a removable connection point in steel piping systems.

Class 3000 Rating at 150°F

The fitting carries a Class 3000 pressure rating and handles a maximum operating pressure of 2,000 psi at 150 degrees Fahrenheit. Its black forged steel construction resists deformation under sustained loads in Schedule 160 piping, maintaining seal integrity where repeated thermal cycling occurs.

Female Threaded End Configuration

Both ends feature 1-inch FNPT threads, so the union only fits components with matching male threads. Installers requiring socket-weld, butt-weld or different thread sizes must select an alternative fitting type.
