Midland Industries 65778 2in Fpt Merchant Coupling Black Steel

Product Description

The MIDLAND INDUSTRIES 65778 is a 2-inch black steel merchant coupling rated for 150-pound malleable iron service. It features female pipe thread (FPT) connections on both ends, making it a standard threaded union for joining two sections of pipe in-line. The fitting conforms to ANSI B1.20.1 thread standards at a 2-11/2 thread specification, ensuring consistent thread engagement with standard NPT pipe. At 1.035 pounds and compact dimensions, it installs quickly in tight spaces. It is suited for gas, water, and industrial piping systems where black malleable fittings are specified.

This coupling is used in residential and light commercial plumbing, gas distribution, and industrial piping applications where black iron pipe is the standard material. It is commonly installed in natural gas and propane supply lines, as well as hydronic heating and general-purpose water systems. Licensed plumbers, pipefitters, and HVAC technicians regularly use this type of fitting when extending or repairing black iron pipe runs. Its 150-pound pressure class makes it appropriate for standard-pressure service lines found in both new construction and retrofit work.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and IFGC or IPC requirements. Shut off the gas or water supply and relieve system pressure before removing or installing any threaded fitting. Apply a listed thread sealant or PTFE tape rated for the intended service medium to all male threads before assembly. Do not over-tighten; hand-tighten first, then use a pipe wrench for final seating without exceeding snug engagement.
