Anvil 2-1/2" Black Forged Steel Union

The Anvil 0361502008 is a Class 3000 forged steel pipe union built for 2-1/2 inch FNPT connections. It meets ASME B16.11, ASTM A106, B1.20.1 and MSS SP-83 standards for industrial piping systems. This fitting suits installers who need a removable joint rated for high pressure and temperature service.

Forged steel body with FNPT threads

The black forged steel construction withstands 1000 psi at 150 degrees F and 300 psi saturated steam at 550 degrees F. Operating range spans -20 to 550 degrees F. The union measures 5 3/13 inches outside diameter with a 5 15/64 inch hex size and two bolt holes, allowing straightforward assembly and disassembly with standard tools.

Replaces permanent welded or flanged joints

This union upgrades installations where future pipe separation is required for maintenance or equipment swap-outs. The jump is worth it when a system demands a pressure-rated, standards-compliant connection that can be broken and remade without cutting pipe. It is not for lines that will never need disassembly.

Questions about this item

What does the FNPT connection type mean for the 2-1/2" pipe size?

FNPT indicates female National Pipe Taper threads per ASME B1.20.1. The 2-1/2" size refers to the nominal pipe diameter that mates with a matching male NPT thread.

What clearance does the 5 15/64" hex size require for installation?

A wrench or socket must accommodate a 5 15/64" hex across flats. Allow enough swing radius around the union body to engage the hex fully without obstruction.

How do you assemble the three-piece union without cross-threading the ground joint?

Slip the nut onto one pipe, thread the male and female ends onto their respective pipes, then bring the nut forward and tighten it to seat the ground joint faces evenly.
