1 inch x 3-1/2 inch Brass Nipple

1" x 3-1/2" Lead-Free Brass Nipple – Built for High-Performance Connections

The 1" x 3-1/2" brass nipple is designed to deliver dependable service in potable water, hydraulic, and pneumatic systems. Manufactured from lead-free brass, this fitting offers corrosion resistance, pressure durability, and dimensional accuracy for applications requiring secure threaded connections.

Key Performance Features

• Material Grade: Constructed from lead-free brass, compliant with federal Safe Drinking Water Act (SDWA) regulations for potable systems.
• Thread Compatibility: Precision-machined NPT threads ensure a tight, leak-resistant seal in both residential and commercial installations.
• Mechanical Strength: Resists deformation under torque and pressure, maintaining joint integrity over long-term service.
• Corrosion Resistance: Brass resists internal and external corrosion in a wide range of water and air systems, reducing the risk of fitting failure.
• Versatility: Suitable for use in water distribution, air compressor lines, irrigation, and industrial plumbing setups.

Specifications

• Nominal Size: 1 inch
• Length: 3-1/2 inches
• Material: Lead-Free Brass (per ASTM B584 or equivalent)
• Thread Type: NPT Male x NPT Male
• Certification: NSF/ANSI 61 and NSF/ANSI 372 for use in potable water systems

Installation Guidelines

• Use PTFE thread sealant or approved pipe dope to ensure leak-free joints.
• Avoid over-tightening to prevent thread deformation or damage to mating components.
• Verify compatibility with pipe material and local code requirements for water quality and pressure ratings.

Common Applications

This brass nipple is frequently used in plumbing systems to extend pipe runs, adapt threaded fittings, or facilitate flow transitions. It is well-suited for potable water service lines, mechanical rooms, pump stations, and maintenance applications requiring high mechanical reliability and regulatory compliance.

Did You Know?

Lead-free brass formulations, defined as containing no more than 0.25% lead, are now mandated in all fittings used for drinking water systems under the Reduction of Lead in Drinking Water Act (2014).

Professionals rely on lead-free brass nipples like this one for consistent performance and long service life in demanding plumbing environments. For strength, safety, and regulatory peace of mind, choose fittings engineered to meet today's toughest standards.
