1 inch x 5 inch Brass Nipple

1" x 5" Brass Nipple – Threaded Connector for Potable Water and Mechanical Systems

The 1" x 5" brass nipple is a straight pipe fitting designed for joining two female-threaded components in plumbing, HVAC, and general utility piping systems. Machined from lead-free brass, this fitting provides a corrosion-resistant, pressure-rated solution for potable water and other approved applications. Threads are manufactured to ANSI/ASME B1.20.1 standards for compatibility with NPT pipe systems.

Technical Specifications

• Material: Lead-free brass (typically CW510L or equivalent; NSF/ANSI 61 and 372 compliant)
• Nominal Size: 1 inch
• Length: 5 inches overall
• Connection Type: NPT (male x male), tapered threads per ANSI/ASME B1.20.1
• Wall Thickness: Schedule 40 (standard weight)
• Operating Pressure: Suitable for systems rated up to 200–300 psi depending on configuration
• Temperature Range: Up to 400°F for non-steam liquid service

Installation Guidelines

Before installation, ensure that threads are clean and properly aligned. Use PTFE tape or compatible thread sealant rated for brass-to-metal joints. Tighten with a pipe wrench per recommended torque values for 1" brass NPT fittings to ensure leak-free operation. Avoid over-torquing to prevent thread deformation.

Common Applications

This brass nipple is used in:

• Potable water distribution systems
• Mechanical room piping and control manifolds
• HVAC system supply and return lines
• Compressed air, low-pressure steam (when approved), and industrial liquid conveyance

Material Consideration

Lead-free brass fittings provide excellent corrosion resistance and are compliant with federal regulations for potable water use. They are suitable for both indoor and exterior protected installations. In high-chloride or aggressive chemical environments, verify brass compatibility or consider alternate alloys.
