3/4 inch x 1/2 inch Galvanized Iron Reducing Coupling Female x Female

3/4 inch x 1/2 inch Galvanized Iron Reducing Coupling – Threaded FPT x FPT

The 3/4 inch x 1/2 inch galvanized iron reducing coupling is a female-threaded fitting used to connect two pipes of different nominal sizes in a straight-line configuration. Manufactured from malleable iron and hot-dip galvanized for corrosion resistance, this fitting is designed for use in pressure-rated water, air, and gas distribution systems.

Engineered in accordance with ANSI and ASTM dimensional standards, this reducing coupling ensures consistent engagement and sealing performance. It is typically installed in commercial, residential, and industrial piping systems requiring a transition between 3/4 inch and 1/2 inch nominal pipe sizes.

Key Product Features

• ✅ Nominal Sizes: 3/4 inch x 1/2 inch Female NPT x Female NPT
• ✅ Material: Malleable Iron with Hot-Dip Galvanized Coating
• ✅ Connection Type: Threaded Ends per ANSI/ASME B1.20.1
• ✅ Use Case: Reduces pipe diameter in straight-run connections without requiring additional adapters
• ✅ Corrosion Protection: Zinc coating resists rust in non-potable water and low-humidity environments

Installation Guidelines

Apply PTFE tape or thread sealant to male pipe threads prior to assembly. Hand-tighten and use a pipe wrench to finish installation while ensuring not to overtighten. This fitting is intended for systems using Schedule 40 or equivalent threaded pipe. Always verify material compatibility and follow local code requirements for system design and inspection.

Typical Applications

Commonly used in branch line reductions, utility piping, water service risers, and compressed air systems. Appropriate for installations in mechanical rooms, utility closets, and distribution lines requiring a direct pipe size transition.

Material Notes

Galvanized iron fittings are manufactured for non-potable water systems and dry gas applications. Not recommended for use in potable water systems unless explicitly approved by local code due to potential zinc leaching over time.
