1/4 inch x 3-1/2 inch Brass Nipple

1/4" x 3-1/2" Brass Pipe Nipple – Lead-Free, Threaded Connection

The 1/4" x 3-1/2" brass nipple is a straight-length fitting used for extending pipe runs or connecting two female-threaded components in pressurized plumbing systems. Manufactured from lead-free brass, it meets safety requirements for potable water and offers resistance to corrosion and mechanical wear.

Product Application

Commonly used in potable water, air, oil, or non-corrosive fluid systems, this brass nipple provides a versatile solution for pipe extensions, spacing, or threaded transitions. It is suitable for residential, commercial, and light industrial applications involving copper, CPVC, or galvanized connections through threaded fittings or adapters.

Technical Specifications

• Material: Lead-free brass (compliant with NSF/ANSI 61 & 372)
• Nominal Size: 1/4 inch
• Length: 3-1/2 inches
• Thread Type: Male NPT (National Pipe Tapered Threads)
• Pressure Rating: Suitable for low to moderate pressure systems

Installation Information

Threaded installation requires the use of an appropriate thread sealant or PTFE tape to ensure a watertight seal. Threads should be engaged fully using a wrench with care taken to avoid over-tightening, which may damage female components or the fitting itself. Ensure alignment and support of adjacent piping to avoid mechanical stress.

Performance and Use

Engineered to maintain structural and hydraulic integrity over time, this fitting supports consistent pressure containment and resists dezincification in potable water systems. It is commonly used in distribution manifolds, fixture branches, appliance connections, and mechanical assemblies.

Standards and Compliance

This fitting complies with applicable codes and standards for potable water use, including lead-free content requirements per the U.S. Safe Drinking Water Act. It is suitable for use in systems governed by UPC, IPC, and state plumbing codes where NSF-listed fittings are required.
