1/8 inch Galvanized Iron Coupling Female x Female

1/8" Galvanized Iron Coupling – Precision Connection for Small-Diameter Systems

The 1/8" Galvanized Iron Coupling is engineered to deliver a secure and long-lasting connection between two male-threaded pipes. This fitting is specifically designed for small-bore systems where corrosion resistance and reliable sealing are critical. Ideal for use in air, gas, and low-pressure liquid service lines, it is built to meet the requirements of commercial-grade applications.

Advantages of High-Quality Galvanized Couplings

• Corrosion-Resistant Coating: Hot-dip galvanized finish enhances resistance to rust and oxidation in moist or humid conditions.
• Consistent Thread Engagement: Threads conform to ANSI B1.20.1 NPT standards, ensuring a leak-tight seal and uniform torque resistance across all installations.
• Compact Design: Optimized for close-quarters assembly in constrained piping configurations.
• Material Integrity: Manufactured from ASTM A197 malleable iron, combining durability with machinability for accurate thread production.

Product Specifications

• Nominal Size: 1/8 inch
• Material: Malleable iron with hot-dip galvanized finish
• Connection Type: Threaded (FIP x FIP)
• Standards: ASME B16.3 compliant; threads per ANSI B1.20.1

Installation Recommendations

Install using pipe thread sealant or PTFE tape to ensure leak-free joints. Do not over-torque—follow manufacturer-recommended torque values to prevent thread deformation. Proper pipe alignment during assembly is essential for sealing integrity and long-term serviceability.

Application Scope

The 1/8" galvanized coupling is commonly used in small-diameter plumbing lines for:

• Compressed air systems
• Low-pressure gas service
• Water distribution lines
• Hydronic heating control branches

Did You Know?

Galvanized malleable iron couplings provide a balance of structural resilience and corrosion protection, making them an industry-standard choice for long-term reliability in non-potable systems.

Choose the 1/8" Galvanized Iron Coupling for a high-integrity solution that supports precise assembly, long service life, and secure sealing in compact line configurations.
