Midland Industries 79774 Aluminum Half Coupling 3/4 in Fpt

Product Description

The MIDLAND INDUSTRIES 79774 is an aluminum half coupling designed to provide a female pipe thread (FPT) connection point in piping assemblies. Half couplings are used when only one end of a fitting needs to mate with a threaded pipe or fitting, leaving the opposite end open for welding or direct attachment to a vessel, tank, or flat surface. This fitting features a 3/4-14 thread (NPT) on its FPT end. At 0.05 pounds, it is a lightweight component suited for low-load plumbing, pneumatic, and general fluid-handling applications. Plumbers, pipefitters, and industrial maintenance technicians are the typical installers.

This half coupling is appropriate for residential and light commercial piping systems where aluminum fittings are specified. Common applications include low-pressure air lines, water distribution branch points, and pneumatic system assemblies where a threaded female port is needed at a welded or flanged connection. The 3/4 in FPT connection accepts a standard 3/4 in male NPT pipe end. Its aluminum construction makes it suitable for corrosion-resistant installations where steel fittings are not preferred.

Key Features

• 3/4 in FPT connection with 3/4-14 NPT thread for standard pipe compatibility
• Aluminum construction provides corrosion resistance and reduced weight
• Half-coupling design for single-end threaded connections to tanks, vessels, or surfaces
• Compact footprint: 1.25 inches length, 1.25 inches width, 0.7 inches height
• Lightweight at 0.05 pounds, reducing load in overhead or weight-sensitive assemblies

Compatibility

Designed as a standard aluminum half coupling for use with 3/4 in male NPT threaded pipe in general plumbing, pneumatic, and fluid-handling piping systems.

Installation Notes

Installation is typically performed by a licensed plumber or pipefitter. Shut off and depressurize the system completely before installing or removing any fitting. Apply appropriate thread sealant or PTFE tape to mating male threads per the applicable piping code. Do not overtighten aluminum fittings, as the material is softer than steel and susceptible to thread damage under excessive torque.
