1/4 inch Brass Coupling Female x Female

1/4 inch Lead-Free Brass Coupling – Straight Connector for Potable and Non-Potable Systems

The 1/4 inch Lead-Free Brass Coupling is a straight, internally threaded fitting designed to join two 1/4 inch male-threaded components in fluid conveyance systems. Commonly used in potable water lines, refrigeration setups, and low-pressure air applications, this coupling ensures corrosion resistance, mechanical strength, and compliance with lead-free regulations for drinking water use.

Manufactured from lead-free brass in compliance with NSF/ANSI 61 and 372, this coupling provides a secure, NPT-threaded connection that supports maintenance and assembly operations in confined spaces or critical service branches.

Key Features

• ✅ Lead-Free Brass Alloy: Meets federal and state standards for use in potable water applications under the Safe Drinking Water Act.
• ✅ Female NPT x Female NPT: Compatible with 1/4 inch NPT threaded pipe, tubing adapters, or valves.
• ✅ Corrosion-Resistant: Suitable for use in water distribution, compressed air, and non-corrosive fluid transfer lines.
• ✅ Compact Design: Ideal for use in tight configurations or assemblies requiring minimal fitting footprint.
• ✅ Temperature and Pressure Rated: Designed for performance in typical plumbing environments up to 200 PSI and 180°F (depending on system design).

Specifications

• Nominal Size: 1/4 inch
• Connection Type: FPT x FPT (NPT – ANSI B1.20.1)
• Material: Lead-Free Brass (typically C46500 or equivalent)
• Certifications: NSF/ANSI 61 & 372 for potable water applications

Installation Guidelines

Install using approved thread sealant or PTFE tape compatible with the system medium. Tighten using an appropriately sized wrench to prevent thread damage and ensure seal integrity. Do not overtighten. This fitting should only be used within its rated temperature and pressure parameters as defined by applicable system standards.

Typical Applications

Used in domestic water supply lines, beverage dispensing equipment, pneumatic control lines, and appliance hookups where a compact threaded union is required. Frequently specified in retrofit assemblies or systems that require disconnection and reassembly for service access.

Regulatory Note

Lead-free brass couplings are required in drinking water systems per U.S. federal law and most local plumbing codes. Always confirm material certification and system compatibility during project design or component substitution.

The 1/4 inch Lead-Free Brass Coupling is a compact, standards-compliant connector used to ensure secure threaded unions in fluid-handling systems. Its durable construction and certified composition make it suitable for professional-grade applications across a variety of sectors.
