1-1/4 inch x 3 inch Brass Nipple

1-1/4" x 3" Brass Pipe Nipple – Machined for Commercial-Grade Performance

The 1-1/4" x 3" Brass Nipple is manufactured from corrosion-resistant, lead-free brass for dependable use in potable water systems, HVAC circuits, and general-purpose fluid transfer. With National Pipe Taper (NPT) threads on both ends, it delivers a rigid, pressure-rated connection ideal for joining two female-threaded components.

This fitting is commonly used in both residential and commercial mechanical systems where a short, robust extension or coupling segment is needed. Its solid brass construction ensures long service life and mechanical integrity in high-usage environments.

Key Advantages

• Lead-Free Brass – Complies with federal Safe Drinking Water Act (SDWA) standards for potable water applications
• Machined NPT Threads – Ensures secure, leak-resistant joints with compatible female-threaded fittings
• Resists Dezincification – Suitable for use in aggressive water conditions, reducing failure risks
• Pressure-Ready – Appropriate for systems handling water, air, oil, or non-corrosive fluids under typical pressure loads

Specifications

• Material: Lead-Free Brass (typically C46500 or equivalent)
• Size: 1-1/4" nominal diameter x 3" overall length
• Thread Standard: ANSI/ASME B1.20.1 NPT
• Pressure Rating: Suitable for up to 125 psi at ambient temperature (verify system-specific requirements)
• Certification: NSF/ANSI 61 & 372 compliant for drinking water system components

Installation Guidance

Apply thread sealant or PTFE tape to both ends during assembly to ensure a watertight and air-tight seal. Wrenches should be used with care to avoid thread galling or deformation. Inspect for thread damage before installation and pressure test system components according to local codes and specifications.

Typical Applications

• Potable water supply systems
• Chilled and heated water HVAC systems
• Low-pressure compressed air systems
• General utility connections in mechanical rooms

Industry Insight

Brass pipe nipples are preferred in systems requiring chemical resistance and stable thermal expansion properties. Their ability to maintain structural integrity in hot and cold water circuits makes them a standard component in professional-grade plumbing installations.

Install the 1-1/4" x 3" Brass Nipple for a durable, code-compliant connection that withstands the demands of modern fluid-handling systems. Its precision-threaded design and lead-free construction offer the performance and reliability that professionals require in high-usage environments.
