1/4 inch x 4-1/2 inch Brass Nipple

1/4" x 4-1/2" Brass Pipe Nipple – Precision-Threaded Connector for Potable and Utility Systems

The 1/4" x 4-1/2" Brass Nipple is a close-tolerance, male-threaded fitting designed for joining two female-threaded components within compact or linear plumbing assemblies. Manufactured from lead-free brass, this component is suitable for potable water applications, as well as non-potable systems such as air, oil, and hydraulic lines.

Engineered for high-integrity system performance, the brass nipple provides excellent corrosion resistance, mechanical strength, and pressure containment. It is ideal for conditions requiring long service life with minimal degradation, even in chemically variable environments or systems subject to frequent cycling.

Performance and Material Specifications

• Material: Lead-free brass, conforming to ASTM B62 or equivalent
• Nominal Size: 1/4 inch
• Length: 4-1/2 inches (overall thread-to-thread dimension)
• Connection Type: NPT (male x male, tapered pipe thread)
• Pressure Rating: Suitable for applications up to 1,200 PSI (non-shock water, oil, air)
• Temperature Range: -65°F to 250°F (-54°C to 121°C)
• Compliance: NSF/ANSI 61 & 372 certified for use in potable systems

Installation Guidelines

This component should be installed using thread sealant tape or approved pipe joint compound to ensure a leak-proof connection. Over-tightening should be avoided to prevent thread galling or cracking in soft brass mating components. For pressurized systems or code-regulated installations, qualified personnel should perform pressure testing after assembly.

Typical Applications

The 1/4" x 4-1/2" brass nipple is commonly used in:

• Water supply lines and fixture risers
• Low-pressure hydraulic systems
• Fuel-oil distribution piping
• Compressed air and gas manifolds
• Instrumentation and control system hook-ups

Code Considerations

In accordance with the Safe Drinking Water Act (SDWA), lead-free brass must be used in plumbing systems carrying potable water. This nipple complies with current U.S. plumbing codes and is certified for use in all 50 states.

Whether you’re fabricating custom assemblies or performing repairs in tight spaces, the 1/4" x 4-1/2" Brass Nipple delivers the reliability and performance expected in professional-grade mechanical systems. Specify this fitting where space constraints demand a compact, corrosion-resistant solution.
