1-1/2 inch Brass Coupling Female x Female

1-1/2 inch Lead-Free Brass Coupling – FPT x FPT Connector for Potable Water Systems

The 1-1/2 inch Lead-Free Brass Coupling is a female threaded (FPT x FPT) fitting used to join two sections of male-threaded pipe in water distribution systems. Manufactured from lead-free brass to meet potable water application standards, this fitting is suitable for both new installations and system retrofits where full compliance with NSF/ANSI 61 and 372 is required.

Commonly used in copper, CPVC, or galvanized transitions where threaded brass connections are necessary, this coupling offers a mechanically sound and corrosion-resistant solution in residential, commercial, and light industrial environments.

Product Features

• ✅ Material: Lead-free brass conforming to ASTM B584 (C69300 or equivalent alloy).
• ✅ Thread Type: NPT female threads on both ends for compatibility with standard male-threaded pipe or adapters.
• ✅ Temperature and Pressure: Rated for working pressures up to 200 PSI and service temperatures up to 180°F in water systems.
• ✅ Compliance: NSF/ANSI 61 and NSF/ANSI 372 certified for potable water use; meets federal and state lead-free mandates.
• ✅ Application Flexibility: Used in both hot and cold water supply lines, pump connections, meter assemblies, and repair unions.

Installation Notes

For optimal performance, threaded connections should be sealed using PTFE tape or approved thread sealant. Avoid over-torquing during assembly to prevent thread deformation. Installation should follow local plumbing code and system specification requirements, especially in systems subject to inspection or certification.

Typical Applications

This 1-1/2 inch lead-free brass coupling is used in plumbing systems that require a safe, corrosion-resistant threaded union for potable water. Applications include municipal water distribution lines, mechanical room piping, meter installations, and transition joints in both residential and commercial buildings.

Regulatory Insight

Federal legislation (Reduction of Lead in Drinking Water Act) mandates that all fittings used in potable water systems meet “lead-free” standards, defined as a weighted average of less than 0.25% lead across wetted surfaces. This coupling meets or exceeds all current regulatory requirements for such installations.
