1/4 inch x 5 inch Brass Nipple

1/4" x 5" Brass Pipe Nipple – Precision-Threaded for Secure, Corrosion-Resistant Connections

The 1/4" x 5" Brass Nipple is a straight, close-tolerance fitting designed for joining two female-threaded components in plumbing, mechanical, or compressed air systems. Manufactured from lead-free brass, this component is suitable for potable water lines and is also commonly used in non-potable fluid or gas systems requiring durability and resistance to corrosion.

This fitting offers high tensile strength and a strong resistance to dezincification, making it suitable for both indoor and outdoor use, including corrosive environments. Its threaded design allows for straightforward assembly using NPT (National Pipe Thread) tapered threads, which are standard for U.S. pipe connections.

Key Specifications

• Material: Lead-free brass (in compliance with NSF/ANSI 61 & 372)
• Size: Nominal 1/4 inch diameter, 5 inches overall length
• Thread Type: Male NPT, both ends
• Temperature Range: -65°F to 250°F (-54°C to 121°C)
• Pressure Rating: Suitable for up to 1,200 PSI (non-shock water, air, oil)

Installation Guidelines

For proper installation, apply thread sealant tape or pipe joint compound to all male threads before assembly. Avoid overtightening, especially when threading into brass or softer metal components. Brass is less prone to thread galling compared to stainless steel, but care should still be taken to avoid cross-threading or thread deformation.

Common Applications

• Potable water systems
• Compressed air lines
• Low-pressure steam and gas service
• Hydronic heating loops
• Instrumentation and control circuits

Advantages of Lead-Free Brass Construction

• Corrosion Resistance: Maintains mechanical integrity and thread quality over time in wet environments.
• Compliance: Meets federal and state mandates for lead-free components in potable water systems.
• Machinability: Brass allows for precise threading and repeatable engagement without excessive tool wear.

Code Note

Lead-free brass nipples are now required by federal law for any component in contact with potable water systems per the Reduction of Lead in Drinking Water Act (2014), and meet NSF/ANSI 61 and 372 standards.

The 1/4" x 5" Brass Pipe Nipple is an ideal solution for tight-space connections and linear system extensions in professional installations. It offers the mechanical reliability and compliance necessary for both new construction and retrofit applications.
