1/2 inch Brass Compression Union Compression x Compression

1/2 inch Compression Union – Lead-Free Brass for Mechanical Pipe Connections

The 1/2 inch Compression Union is engineered for joining two sections of pipe without soldering, making it ideal for potable water applications where ease of installation and future disassembly are required. Constructed from lead-free brass, it is suitable for use in both new construction and retrofit scenarios across commercial and residential systems.

This union provides a mechanical seal through compression, eliminating the need for heat or adhesives. It is compatible with copper, CPVC, and other rigid piping systems when used with appropriate inserts or bushings as required by local plumbing codes.

Installation Guidance

Ensure tubing is cut square, clean, and free of burrs. Slide compression nut and ferrule onto the pipe before inserting into the fitting body. Tighten using appropriate wrenches to compress the ferrule against the pipe and form a mechanical seal. Do not over-tighten. Use of plumber’s tape is not required on compression threads. Follow all relevant plumbing codes and consult manufacturer guidance for compatibility with specific piping materials.

Common Applications

Regularly used in domestic water systems, valve shutoffs, appliance hookups, and branch line transitions. Its reusability makes it suitable for maintenance areas, fixture replacements, and upgrades where soldering is not feasible or desirable.

Code Compliance Note

Federal and state plumbing codes mandate the use of lead-free components in drinking water systems. This union conforms to Safe Drinking Water Act requirements and is certified accordingly.

For mechanical joining applications requiring repeatability and code-approved materials, the 1/2 inch Brass Compression Union offers a robust and efficient solution for professional plumbing installations.
