3/4 inch x 5 inch Brass Nipple

3/4" x 5" Brass Nipple – Lead-Free, Threaded Pipe Fitting

The 3/4" x 5" brass nipple is a straight pipe fitting with male NPT threads on both ends, designed to connect female-threaded components in pressure-rated piping systems. Manufactured from lead-free brass in accordance with ASTM and ANSI standards, it is suitable for potable water, air, and other non-corrosive fluid systems.

This fitting is used to extend piping runs, provide spacing between components, or connect valves, couplings, and other fittings. Its corrosion-resistant properties and dimensional consistency make it appropriate for both residential and commercial installations.

Key Performance Features

• ✅ Material: Lead-free brass (typically UNS C69300 or equivalent), compliant with NSF/ANSI 61 and 372 for potable water use.
• ✅ Thread Type: National Pipe Taper (NPT) threads on both ends, machined to ANSI/ASME B1.20.1 for sealing reliability.
• ✅ Corrosion Resistance: Brass resists dezincification and oxidation in fluid and air systems.
• ✅ Standard Length: 5" overall length for use in spacing, offsets, and system tie-ins.
• ✅ Pressure Service: Rated for use in moderate-pressure systems depending on media, temperature, and wall thickness.

Installation Considerations

Install using thread sealant or PTFE tape to prevent leakage. Use pipe wrenches on unthreaded sections to avoid thread deformation. Confirm that the fitting material is compatible with the media in service and that installation complies with applicable local codes and plumbing system design requirements.

Common Applications

Typical installations include domestic water supply systems, compressed air lines, and utility piping in both residential and commercial buildings. This fitting is frequently used in meter connections, fixture branches, and between valves and manifold systems.

Material Compliance

Lead-free brass nipples are required in potable water systems by the Safe Drinking Water Act (SDWA) and certified under NSF/ANSI 61 and NSF/ANSI 372. These certifications ensure material safety and code acceptance for drinking water distribution systems.
