3/8 inch x Close Chrome-Plated Brass Nipple

3/8" Lead-Free Brass Pipe Nipple – Threaded Fitting for Potable Water and Mechanical Systems

The 3/8" Lead-Free Brass Nipple is a straight pipe fitting used to join two female-threaded components in fluid, gas, or mechanical piping systems. Precision-machined and fabricated from compliant low-lead brass, this nipple is suitable for use in potable water systems and other general-purpose applications requiring corrosion resistance and high mechanical integrity.

Manufactured in accordance with ANSI/ASME B1.20.1 (NPT thread specification) and NSF/ANSI 61 and 372 for lead-free compliance, the fitting is designed for both residential and commercial use in pressurized and non-pressurized systems. Brass construction offers excellent resistance to dezincification and thermal stress, extending service life in varied environmental conditions.

Technical Specifications

• Nominal Size: 3/8 inch
• Material: Lead-Free Brass (typically alloy C69300 or C46500)
• Connection Type: Male NPT x Male NPT
• Length: Varies by model (typically close, short, or extended)
• Standards Compliance: NSF/ANSI 61, NSF/ANSI 372, ANSI B1.20.1
• Pressure Rating: Up to 200–300 PSI depending on temperature and application

Installation Guidelines

Install using standard pipe wrenches and an appropriate thread sealant or PTFE tape approved for the system media. Tighten to recommended torque values to avoid thread distortion. Brass nipples should not be mixed directly with incompatible metals (e.g., aluminum) without dielectric separation in corrosive or electrochemical environments.

Applications

Commonly used in potable water supply systems, hydronic heating loops, air compressor lines, and mechanical equipment connections. Also suitable for use in irrigation, gas distribution (non-industrial), and general utility piping assemblies where lead-free compliance is required.

Material Performance

Lead-free brass exhibits strong resistance to corrosion, wear, and scaling, and maintains dimensional stability across a wide temperature range. It is compatible with copper, CPVC, and other standard piping materials when properly installed and isolated where required.
