3/8 inch x 5 inch Chrome-Plated Brass Nipple

3/8" x 5" Lead-Free Brass Pipe Nipple – Threaded Connector for Potable and Mechanical Systems

The 3/8" x 5" Brass Pipe Nipple is a straight-threaded fitting designed for joining two female-threaded components in potable water, HVAC, air, and fluid distribution systems. Manufactured from lead-free brass in compliance with NSF/ANSI 61 and 372, this nipple provides a corrosion-resistant, pressure-rated connection suitable for both residential and commercial use.

Its full-length male National Pipe Taper (NPT) threads ensure consistent engagement and reliable sealing in standard piping assemblies. The 5-inch length offers flexibility in installations where extended reach or spacing between fittings is required.

Key Features

• ✅ Lead-Free Brass Composition Compliant with federal Safe Drinking Water Act for use in potable water systems.
• ✅ Precision-Machined NPT Threads Tapered for pressure-tight joints using approved thread sealants.
• ✅ Uniform Wall Thickness Supports consistent pressure ratings and minimizes flow restriction.
• ✅ Corrosion-Resistant Suitable for use with water, air, oil, and non-aggressive chemicals in above-ground systems.

Technical Specifications

• Material: Lead-free brass (typically compliant with ASTM B62 or equivalent)
• Nominal Size: 3/8 inch
• Overall Length: 5 inches
• Thread Type: Male NPT (both ends)
• Certifications: NSF/ANSI 61 and NSF/ANSI 372 certified for potable water applications

Installation Guidelines

Threaded ends should be cleaned and sealed with PTFE tape or approved joint compound prior to assembly. Apply torque with an appropriate wrench at the hex or wrench flats if present, avoiding overtightening to prevent damage to the threads or mating components. Verify compatibility with the system’s pressure and temperature requirements before installation.

Common Applications

This brass nipple is typically used in water heater connections, control valves, mixing stations, and general utility piping where reliable spacing or alignment of components is required. Also suitable for use in air lines, gauge installations, and corrosion-sensitive service environments.

The 3/8" x 5" Lead-Free Brass Nipple provides a durable, code-compliant threaded solution for professional-grade installations across plumbing, HVAC, and mechanical systems.
