3/4 inch x 4 inch Brass Nipple

3/4" x 4" Brass Pipe Nipple – Precision-Machined for High-Integrity Connections

The 3/4" x 4" Brass Pipe Nipple is manufactured from lead-free brass and engineered for use in potable water, oil, air, and other fluid conveyance systems. With precision-cut male threads on both ends, it offers a secure and consistent connection in both low- and moderate-pressure systems. Suitable for commercial and industrial-grade applications, this fitting supports compliance with current plumbing and mechanical codes.

This component is machined from solid brass rod stock for structural consistency, minimizing thread galling during installation. Its corrosion-resistant properties make it ideal for use in systems exposed to moisture or variable temperature environments. Brass is also non-magnetic and provides natural antimicrobial benefits when used in potable water lines.

Product Advantages

• ✅ Threaded Male Ends – NPT (National Pipe Tapered) threads ensure tight mechanical sealing with compatible components.
• ✅ Solid Brass Construction – Provides high resistance to dezincification and stress corrosion cracking.
• ✅ Lead-Free Compliance – Conforms to NSF 61 and ANSI 372 standards for use in drinking water systems.
• ✅ Machined Tolerances – Designed for optimal alignment and engagement with female-threaded fittings.
• ✅ High Thermal Stability – Suitable for hot and cold water distribution as well as hydronic heating systems.

Specifications

• Nominal Size: 3/4 inch
• Overall Length: 4 inches
• Thread Type: Male NPT
• Material: Lead-free brass (CW510L or equivalent)
• Operating Pressure: Rated up to 200 PSI depending on system design

Applications

Commonly installed in potable water distribution, low-pressure air and oil systems, and mechanical pipe networks. Appropriate for both interior and exterior applications where corrosion resistance and code compliance are required. Frequently used in valve terminations, fixture offsets, and transitional pipe sections.

Additional Notes

Ensure proper thread sealing compound or PTFE tape is used during installation. Avoid overtightening to maintain thread integrity and prevent deformation. When used in mechanical room settings or pressurized systems, verify torque specs per local code and manufacturer guidance.

The 3/4" x 4" Lead-Free Brass Nipple provides long-term durability, code compliance, and performance reliability essential for professional-grade plumbing projects. An excellent solution for installations where consistent quality and material compatibility are critical.
