2 inch Galvanized Iron Union Female x Female

2 inch Galvanized Iron Union – Threaded Fitting for Serviceable Connections

The 2 inch Galvanized Iron Union is a mechanical fitting designed to allow easy disassembly and reconnection of threaded piping systems. It provides a serviceable joint, ideal for systems requiring periodic maintenance or future modifications without cutting pipe.

Constructed from cast galvanized iron and featuring threaded female ends, this union supports fluid-tight connections in pressurized systems. Its corrosion-resistant zinc coating enhances longevity in water, air, and non-corrosive gas applications.

Key Features and Performance Benefits

• ✅ Hot-Dip Galvanized Body Provides corrosion protection in wet or humid environments, extending service life in both indoor and outdoor installations.
• ✅ Precision-Machined Threads Manufactured to National Pipe Taper (NPT) standards, ensuring compatibility with schedule 40 steel or galvanized pipe.
• ✅ Removable Union Nut: Allows for future access and service without disturbing the pipe alignment on either side of the joint.
• ✅ Pressure-Ready Design Suitable for systems operating under moderate to high pressure, including mechanical, plumbing, and industrial water lines.
• ✅ Code-Compatible Construction Made with lead-free materials in accordance with plumbing system regulations for potable and non-potable use.

Installation Guidelines

Installation of a union fitting requires proper thread preparation and alignment. Use thread sealant or PTFE tape on male threads to ensure a leak-free seal. Final tightening should be performed with appropriate torque using pipe wrenches, avoiding over-torquing that could damage threads or distort the union seat.

Application Scope

This union is widely specified in commercial and residential plumbing systems for branch line access, shut-off isolation points, and water heater connections. It also serves in HVAC piping, utility lines, and areas requiring future system flexibility without pipe cutting.

Material Performance Note

Galvanized iron is commonly selected in steel-based piping systems for its resistance to oxidation and its ability to maintain mechanical integrity under mechanical loads and moisture exposure. It remains a cost-effective choice for non-corrosive media distribution lines.
