1/4 inch x Close Brass Nipple

1/4" Lead-Free Brass Nipple – Precision-Forged for Durable, Code-Compliant Connections

The 1/4" Lead-Free Brass Nipple is engineered to deliver high-performance connections in potable water and low-pressure fluid systems. Manufactured from corrosion-resistant, lead-free brass, this fitting offers a reliable solution for joining two female-threaded components, ensuring longevity in both residential and commercial plumbing applications.

Advantages of Lead-Free Brass Construction

• ✔️ NSF/ANSI 61 Certified – Suitable for use in systems carrying drinking water, in accordance with federal Safe Drinking Water Act (SDWA) requirements.
• ✔️ Corrosion Resistance – Lead-free brass resists dezincification and stress cracking, making it ideal for harsh environments.
• ✔️ Thread Integrity – Machined NPT male threads ensure a tight, leak-free seal with compatible fittings.

Technical Specifications

• Material: Lead-free brass (complies with ASTM B584 and/or UNS C69300)
• Size: 1/4" nominal diameter
• Connection Type: Male National Pipe Thread (NPT) on both ends
• Pressure Rating: Up to 125 PSI for water, oil, or air at ambient temperature (verify application-specific limitations)
• Certifications: NSF/ANSI 61 and 372 compliant for use in potable water systems

Installation Guidance

Install using compatible NPT-threaded fittings. Use PTFE tape or pipe thread sealant to ensure a leak-proof seal. Avoid overtightening to maintain thread integrity and prevent cracking. This component is intended for use in cold and hot water systems, low-pressure gas lines, and other compatible applications where code compliance is required.

Common Use Cases

• Potable water supply lines
• Water heater or softener installations
• Air compressor setups
• Low-pressure hydraulic and pneumatic systems

Did You Know?

All plumbing fittings used in drinking water systems must meet the Reduction of Lead in Drinking Water Act, which limits the lead content in wetted surfaces to a weighted average of 0.25% or less. This nipple meets those standards.

For contractors requiring reliable performance and code-compliant materials, the 1/4" Lead-Free Brass Nipple is a critical component that supports durable and secure installations across a range of fluid handling systems.
