Msi Products Inc A203084816 Reducing Coupling 3x1 Inch 150lb

Product Description

The MSI PRODUCTS INC A203084816 is a 150 lb black malleable iron reducing coupling designed to connect two sections of threaded pipe with different diameters. It provides a straightforward, reliable transition between a 3-inch and a 1-inch pipe size without requiring additional adapters or components. Built to a heavy pattern design, this fitting conforms to ASME B16.3 dimensional standards, ASTM A197 material specifications, and ASME B1.20.1 threading standards. It is rated for 150 to 300 psi service and is suited for plumbing, mechanical piping, and industrial piping systems where a durable, code-compliant iron fitting is required.

This reducing coupling is appropriate for residential and commercial piping applications, including water distribution, gas piping, and general mechanical systems where NPT-threaded iron pipe is specified. The heavy pattern construction makes it a dependable choice for both new installations and retrofit work on existing lines where a size transition is needed. Licensed plumbers and pipefitters are the typical installers. Each unit is sold individually and ships as a single fitting.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and ASME or IFGC standards. Shut off and depressurize the pipe system completely before removing any existing fitting or making new connections. Apply an approved thread sealant or PTFE tape to the male threads before assembly and tighten to snug using a pipe wrench. Do not over-tighten malleable iron fittings, as excessive force can crack the casting.
