1 inch Galvanized Iron Coupling Female x Female

Galvanized Iron Coupling – Threaded Fitting for Pressure Applications

This Galvanized Iron Coupling is manufactured for joining two male-threaded pipe ends in a range of pressurized and non-pressurized piping systems. Constructed from malleable iron and hot-dip galvanized to ASTM A153 standards, it provides corrosion resistance and mechanical strength suitable for potable water, air, oil, or steam systems when permitted by local code.

Designed for both horizontal and vertical installations, this coupling meets applicable dimensional tolerances and threading standards per ASME B16.3 and ANSI/ASME B1.20.1. Threaded female ends ensure compatibility with standard Schedule 40 galvanized or black pipe systems.

Key Technical Features

• ✅ Material Composition Malleable iron body with hot-dip galvanized zinc coating for corrosion protection in damp or exterior environments.
• ✅ Standard Tapered Threads NPT threading conforms to ANSI/ASME B1.20.1 for uniform sealing capability.
• ✅ Pressure Rated Designed for working pressures up to 150 psi (varies by system configuration and fluid type).
• ✅ Mechanical Strength Ideal for use in structural and fluid handling applications requiring durable pipe connections.
• ✅ Compliant Manufacturing Produced under ISO-certified quality systems and industry-regulated specifications.

Application Scope

This galvanized coupling is commonly used in water distribution networks, fire protection lines, air compressor systems, and industrial piping configurations. It is not recommended for underground use unless additional corrosion protection measures are implemented.

Installation Guidance

Threaded pipe connections should be properly cleaned and sealed using approved pipe joint compound or PTFE tape. Tighten with pipe wrenches per standard mechanical practices, ensuring no over-torquing which could lead to thread deformation. Follow project-specific pressure testing protocols after installation.

Field Use and Suitability

Often specified in mechanical specs for commercial facilities, process plants, and equipment rooms, galvanized couplings offer reliable service in non-corrosive fluid systems. They are also used in temporary piping configurations and modular skid units requiring threaded assembly for field adjustability.

Built for Jobsite Reliability

This Galvanized Iron Coupling provides a standardized, dependable solution for joining steel pipe in systems where mechanical strength, corrosion resistance, and code compliance are required. Its field-tested performance makes it a preferred fitting for plumbing, HVAC, and general piping contractors.
