Installation Guidance

Use proper soldering techniques when joining to copper tubing. Ensure the pipe end is clean, reamed, and fluxed before heating. Apply thread sealant or PTFE tape on the male thread prior to making the connection to a threaded fitting. Pressure test systems in accordance with local codes after installation.

Common Applications

This copper adapter is typically used in water distribution systems for residential or light commercial construction. It enables transitions from copper to threaded steel, brass, or other materials, especially at fixture stub-outs, water heater installations, and mixing valve assemblies.

Note:

This fitting is not intended for use in gas applications. Use only in systems where copper and threaded connections are compatible and code-approved.

Engineered for long-term performance in potable water applications, this copper male adapter provides a durable, corrosion-resistant solution for professional-grade plumbing installations.
