3/8 inch x 2 inch Chrome-Plated Brass Nipple

3/8" x 2" Lead-Free Brass Nipple – Machined for Code-Compliant Installations

The 3/8" x 2" Lead-Free Brass Nipple is a straight-threaded fitting used to join female-threaded components in potable water and hydronic systems. This component is precision-machined from lead-free brass to meet current federal and state regulations for drinking water applications, offering reliability in systems subject to pressure and thermal variation.

Specifications

• Size: 3/8" nominal diameter x 2" overall length
• Material: Lead-free brass (≤0.25% Pb by weight)
• Thread Type: NPT (National Pipe Tapered Thread), male x male
• Pressure Rating: Suitable for systems up to 200 psi
• Certifications: Complies with NSF/ANSI 61, NSF/ANSI 372, and Safe Drinking Water Act (SDWA) requirements

Performance Advantages

• Corrosion Resistance: Brass composition resists dezincification and galvanic reaction in multi-metal systems
• Pressure Handling: Maintains seal integrity in standard municipal and private water distribution systems
• Versatility: Compatible with hot and cold potable water, hydronic heating, and low-pressure gas installations per code
• Tight Tolerances: Threaded ends conform to ANSI B1.20.1 for consistent thread engagement and seal quality

Installation Guidance

For best results, apply PTFE thread sealant or approved anaerobic thread compound to male threads before threading into mating fittings. Do not over-torque; use hand tightening followed by wrench engagement to the recommended torque per pipe size and material chart. Avoid cross-threading to preserve integrity of NPT seal. Installers should pressure test the system in accordance with local jurisdictional requirements following installation.

Applications

This fitting is typically specified in:

• Potable water supply lines
• Recirculation systems
• Boiler connections and heating system tie-ins
• Transition fittings between copper, CPVC, or PEX adapters

Regulatory Note

Lead-free brass is mandated for use in drinking water systems by the U.S. Safe Drinking Water Act and is required in all 50 states. This nipple conforms to those standards for compliance in residential, commercial, and institutional systems.

The 3/8" x 2" Lead-Free Brass Nipple delivers consistent sealing performance under dynamic system loads and thermal cycling. Its compact length and durable construction make it suitable for confined installations and long-term service in pressure-rated plumbing assemblies.
