1/2 inch x 3-1/2 inch Chrome-Plated Brass Nipple

1/2" x 3-1/2" Chrome-Plated Brass Nipple – Machined for Performance and Code Compliance

The 1/2" x 3-1/2" C/P Brass Nipple is a straight-threaded plumbing fitting manufactured from lead-free brass and finished with a corrosion-resistant chrome plating. It is designed for joining two female-threaded components in potable water systems, fixture risers, or general plumbing assemblies where visual appearance and durability are both required.

Machined to meet NPT (National Pipe Thread) standards, this fitting offers reliable sealing performance when installed with thread compound or tape, making it suitable for high-visibility or exposed piping applications where aesthetics and longevity are important.

Key Features for Field Use

• ✅ Lead-Free Brass Alloy – Complies with national lead content restrictions for components in potable water systems (NSF/ANSI 372 certified).
• ✅ Chrome-Plated Finish – Provides enhanced corrosion resistance and a clean appearance for exposed installations, such as fixture outlets or water heater connections.
• ✅ Full-Pattern Machining – Cut with standard tapered threads (NPT) for secure mechanical joints in residential and commercial service lines.
• ✅ Pressure Rated – Suitable for low to moderate pressure potable water and hydronic systems in accordance with material and thread standards.
• ✅ Versatile Application – Used in transition assemblies, valve risers, tailpiece extensions, and exposed fixture lines.

Technical Specifications

• Material: Lead-Free Brass (chrome plated)
• Size: 1/2" NPT x 3-1/2" length
• Thread Type: Male NPT (National Pipe Thread, ANSI B1.20.1)
• Compliance: NSF/ANSI 61 & 372 (lead-free for potable water)

Installation Guidelines

Threads should be cleaned and sealed using PTFE tape or an approved thread sealant suitable for potable water systems. Avoid over-torqueing to prevent distortion or cracking in adjoining fittings. This nipple is intended for non-flexing, rigid connections and should not be used as a structural component under mechanical strain.

Application Range

Used in residential, commercial, and institutional settings where straight-line connections are required between two threaded fittings. Common in exposed risers, lavatory and sink hookups, and water heater piping where corrosion resistance and compliance are required by code.

Regulatory Insight

Lead-free brass components are required for all potable water contact points under federal regulations and most state plumbing codes. This nipple meets these standards and is certified for use in both new construction and retrofit applications.

The 1/2" x 3-1/2" Chrome-Plated Brass Nipple offers the durability, precision, and compliance required on professional job sites. Engineered for use in high-visibility locations and pressure-rated systems, it supports long-term performance and inspection readiness.
