1 inch Brass Union Female x Female

1 Inch Brass Union – Female x Female, Lead-Free, Threaded Connection

The 1 inch Brass Union Female x Female is a mechanical pipe fitting designed to connect two female-threaded sections of piping. It allows for easy disassembly and reassembly of water or non-potable fluid systems without disturbing the surrounding pipework. Commonly used in maintenance, service access, and system isolation points.

Technical Overview and Material Benefits

This union fitting is precision-machined from lead-free brass and includes a central nut to join the mating halves. It is intended for use in potable water systems, hydronic heating loops, and mechanical assemblies where system integrity and reusability are priorities.

• ✅ Lead-Free Brass Certified to NSF/ANSI 372 and compliant with national lead reduction requirements for potable systems.
• ✅ Female NPT Threads 1 inch nominal size, manufactured to ANSI/ASME B1.20.1 for compatibility with standard threaded pipe and fittings.
• ✅ Corrosion Resistant Brass resists dezincification and degradation in most domestic water and heating system conditions.
• ✅ Reusable Joint Enables separation of piping without cutting, making it ideal for equipment service locations or modular system configurations.

Installation Considerations

Install using two appropriately sized wrenches to hold the union body and tighten the central nut. Apply thread sealant or PTFE tape to the pipe threads per system requirements. Do not overtighten. Inspect for alignment and proper sealing before system pressurization.

• ✅ Tool Requirements: Standard pipe wrenches or adjustable wrenches
• ✅ Sealant: Use thread compound rated for the application medium (potable water, glycol, etc.)
• ✅ Working Pressure: Rated up to 200 PSI (verify per manufacturer specifications)

Common Applications

This union is suitable for use in water heater installations, water distribution manifolds, pressure-reducing valve setups, and system transition points that may require future service. Its Female x Female configuration facilitates flexible system integration where directional flow or equipment connection dictates thread orientation.
