1/2 inch Brass Coupling Female x Female

1/2 Inch Brass Coupling – Female NPT x Female NPT

The 1/2 inch Brass Coupling (FIP x FIP) is a straight-threaded connector designed to join two male NPT-threaded pipes in fluid or gas distribution systems. Manufactured from lead-free brass, this fitting is rated for use in potable water, air, oil, and low-pressure steam applications, and meets applicable plumbing and mechanical standards for durability and performance.

Component Specifications

• ✅ Material: Lead-free brass (compliant with NSF 61 and NSF 372 for potable water use)
• ✅ Thread Type: Female National Pipe Taper (NPT) threads on both ends
• ✅ Nominal Size: 1/2 inch
• ✅ Temperature Rating: Up to 400°F for non-potable applications, depending on system configuration
• ✅ Pressure Rating: Typically rated up to 200–300 PSI depending on temperature and fluid type

Installation Guidance

Install using standard NPT thread practices. Pipe threads should be clean and free of debris. Apply an approved thread sealant or PTFE tape to male threads prior to assembly. Tighten with a properly sized wrench to ensure leak-resistant engagement, taking care not to overtighten to avoid damaging threads.

Use Cases

This coupling is suitable for a wide range of mechanical and plumbing systems, including:

• Potable water supply lines (hot and cold)
• Low-pressure gas distribution (verify local code compliance)
• Compressed air lines
• Hydronic heating systems

Material and System Compatibility

Brass couplings offer excellent corrosion resistance in water and non-corrosive fluid systems. They are also non-magnetic and electrically conductive, which may be advantageous in specific mechanical assemblies. Compatible with copper, brass, and iron pipe materials when used with approved thread sealants.

The 1/2 inch Brass Coupling Female x Female provides a reliable, pressure-rated connection in NPT-threaded piping systems. Its lead-free brass construction ensures long-term performance and compliance with current potable water regulations in both residential and commercial systems.
