Anvil 0390037083 Threaded Reducer 3x2 Malleable Iron

Product Description

The ANVIL 0390037083 is a threaded reducer fitting designed to connect piping runs where a 3-inch line steps down to a 2-inch line using male NPT (MNPT) threads on both ends. Constructed from Class 150 malleable iron and finished in orange, this fitting meets ASTM A47 material standards and carries FM Approval, NSF/ANSI 61 certification, and cULus listing. It is sized at 2.5 inches in height, 3.5 inches in width, and 2.5 inches in length, with a shipping weight of 1.3 pounds. Licensed plumbers and pipefitters specify this reducer for fire protection, industrial, and commercial plumbing systems where a reliable, standards-compliant threaded transition is required.

This fitting is suited for commercial and industrial piping installations where a 3-inch to 2-inch threaded reduction is needed in black iron or malleable iron pipe systems. Typical applications include fire suppression distribution headers, HVAC hydronic piping, and general commercial plumbing service lines. The NSF/ANSI 61 certification makes it appropriate for systems that contact potable water. The FM Approval supports its use in fire protection piping where listed components are required by code.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and NFPA standards for fire protection systems. Isolate and depressurize the pipe system completely before removing or installing any threaded fitting. Apply an approved pipe thread sealant or PTFE tape to the male threads before assembly, and tighten to appropriate engagement without over-torquing, which can crack malleable iron fittings. For fire suppression applications, verify that all installed components carry the required FM or UL listing before system commissioning.
