Msi Products Inc A2230404 Galvanized Iron Coupling 1/4 in

Product Description

The MSI PRODUCTS INC A2230404 is a 1/4 inch, 150 LB galvanized malleable iron full coupling designed to connect two sections of threaded pipe in a straight, secure joint. Built to a heavy-pattern design, it delivers the structural integrity required for demanding piping environments. The galvanized coating provides corrosion resistance that extends service life in harsh or wet conditions. This fitting meets ASME B16.3, ASTM A197, and ASME B1.20.1 standards, and each piece carries full lot traceability with material test reports available on request. Plumbers and pipefitters install this coupling in water, gas, and general mechanical piping systems.

This full coupling is suited for residential and commercial piping applications where two threaded pipe sections need to be joined or an existing pipe run needs to be extended or repaired. Its 150 LB pressure class handles system pressures from 150 to 300 psi, making it appropriate for a wide range of low- to medium-pressure service conditions. The fitting is sold individually and is well-suited for maintenance, repair, and new construction work across plumbing, HVAC, and mechanical systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and IFGC or IPC requirements. Shut off and depressurize the piping system completely before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly, and tighten to snug plus wrench-tight using a pipe wrench. Do not overtighten, as this can crack the fitting body.
