1/2 inch Brass Union Female x Female

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

The 1/2 inch brass union with female National Pipe Thread (NPT) connections is engineered for applications requiring periodic disassembly without cutting into pipe. Constructed from lead-free brass, this union provides a mechanically robust and corrosion-resistant solution suitable for potable water systems and other pressurized fluid installations.

Performance Attributes

• Material: Forged lead-free brass, compliant with NSF/ANSI 61 and NSF 372 for potable water use
• Connection Type: 1/2 inch FNPT x FNPT for standardized compatibility with threaded systems
• Pressure Rating: Up to 200 psi non-shock at ambient temperature
• Temperature Range: Rated for -20°F to 400°F depending on application media and sealant used

Functional Advantages

• Ease of Disassembly: Ideal for service points requiring regular maintenance or modular component changes
• Leak Resistance: Precision-machined threads and central gasket interface ensure a tight, uniform seal
• Corrosion Durability: Brass body provides superior resistance to dezincification and scale buildup in both potable and non-potable applications
• System Flexibility: Supports modular layout changes in distribution systems without pipe cutting or thermal joining

Installation Guidelines

This union should be installed by qualified personnel familiar with threaded brass connections. Proper sealing compounds such as PTFE tape or pipe dope are required to achieve pressure-tight joints. Always verify torque against manufacturer specifications to avoid thread distortion or leaks. Compatible with copper, CPVC, and PEX transition connections where applicable adapters are used.

Typical Applications

• Potable water supply distribution lines
• Boiler and water heater service points
• Mechanical room tie-ins where access is limited
• Hydronic heating system components

Note:

Lead-free brass fittings are mandatory under federal Safe Drinking Water Act (SDWA) regulations for all potable water systems in the U.S., making this union a compliant choice for both new installations and retrofits.
