1/4 inch Copper Adapter Fitting x Male

1/4 inch Copper Male Adapter – Lead-Free Sweat x MIP for Code-Compliant Connections

The 1/4 inch Copper Male Adapter is designed to transition copper tubing to threaded piping systems, providing a durable, lead-free connection point in potable water and HVAC applications. Manufactured from high-purity copper alloys and built to ASME and NSF standards, this fitting delivers reliability where consistent flow and code compliance are essential.

Key Performance Features

• Material: Wrought copper or cast copper alloy (typically alloy C12200 or equivalent)
• Connection Type: Female sweat (solder) x 1/4 inch Male NPT
• Standards: Compliant with ASME B16.22 and NSF/ANSI 61 & 372 for use in potable systems
• Operating Pressure: Suitable for up to 200 psi in typical plumbing installations
• Temperature Range: Withstands continuous use in hot and cold water systems (up to 400°F with proper soldering)

Application Use

This adapter is used to join Type L or M copper tubing to threaded pipe, valves, or equipment. It is commonly installed in domestic water supply, chilled water, boiler feed systems, and low-pressure hydronic circuits. Its compact form and precise machine-cut threads allow for quick connection in tight spaces or retrofit conditions.

Installation Recommendations

Use flux and lead-free solder appropriate for potable applications. Ensure proper pipe preparation—including deburring and cleaning—before sweating. Apply PTFE tape or thread sealant to the male threads to prevent leaks during threaded connection. Do not over-torque, especially when connecting to softer brass or plastic components.

Compliance & Safety

• NSF/ANSI 61-certified for drinking water contact
• NSF/ANSI 372-certified as lead-free (<0.25% weighted average lead content)
• UPC and IPC compliant when installed per manufacturer and local code guidelines

Did You Know?

Per the Reduction of Lead in Drinking Water Act, all fittings used in potable systems must meet NSF 372 certification to be considered lead-free. This adapter qualifies for use in all 50 U.S. states and jurisdictions.

Choose the 1/4 inch Copper Male Adapter when working on systems where long-term reliability, corrosion resistance, and code compliance are critical. Whether used in new construction or system retrofits, this fitting provides a dependable connection that meets the expectations of licensed professionals.
