3/8 inch Galvanized Iron Tee Female x Female x Female

3/8" Galvanized Iron Tee – Precision Threaded Fitting for Branch Line Connections

The 3/8" Galvanized Iron Tee is a malleable iron pressure fitting engineered for the reliable division or extension of piping in low- to moderate-pressure systems. Designed with three female threaded outlets, this tee offers a durable, corrosion-resistant solution for connecting branch lines in potable water, air, gas, or low-pressure steam systems.

Key Performance Advantages

• Hot-Dipped Galvanized Coating: Zinc finish provides enhanced protection against rust and environmental degradation in exposed or moist settings.
• Thread Integrity: NPT (National Pipe Tapered) threads conform to ANSI B1.20.1 for consistent sealing and proper torque engagement.
• Heavy-Duty Body: Malleable iron casting meets ASTM A197 specifications, offering strength and fracture resistance in critical applications.
• Equal Tee Design: Female x Female x Female configuration allows for straightforward integration into existing pipe runs or the creation of new branches.
• High Working Pressure: Suited for systems with working pressures up to 150 psi (dependent on temperature and system type).

Technical Specifications

• Material: Hot-dipped galvanized malleable cast iron
• Nominal Size: 3/8 inch
• Thread Type: FIP x FIP x FIP (ANSI B1.20.1 NPT)
• Compliance: Meets ASME B16.3 and ASTM A153 for zinc coating

Installation Recommendations

Apply PTFE tape or approved thread sealant to male threads before assembly to ensure a leak-free seal. Hand-tighten, then wrench-tighten to manufacturer torque specifications. Do not overtighten to avoid cracking or distorting the fitting. Inspect threads for debris or coating imperfections before use.

Typical Applications

The 3/8" galvanized iron tee is commonly installed in:

• Cold or hot water distribution lines
• Compressed air or vacuum systems
• Fuel gas lines (in compliance with local code)
• Industrial equipment requiring durable branch line connections

Did You Know?

Galvanized iron fittings are often preferred in utility-grade infrastructure due to their ability to resist corrosion in buried or exposed conditions, extending service life and reducing long-term maintenance requirements.

The 3/8" Galvanized Iron Tee delivers robust mechanical strength, corrosion protection, and dimensional accuracy for pressure piping systems. Trusted in industrial, mechanical, and commercial installations, it supports secure branch creation in demanding environments.
