Copper construction for durability: corrosion-resistant copper withstands normal household use, providing a reliable backbone for water distribution.

Convenient single-pack: ready-to-use 1-piece union that fits seamlessly into any 1-1/4" copper run.
Where it shines: ideal for repairing or branching copper supply lines in residential plumbing, water heaters, and hot or cold water runs where a removable joint is advantageous. Use in potable water systems that rely on copper piping, with standard soldering techniques to ensure a tight, leak-free joint.
Practical installation tips:
- Ensure pipes are clean and deburred before soldering; use fresh flux on both pipe and fitting surfaces.
- Dry-fit first to verify alignment and spacing, then assemble with the union nut loosely before completing solder joints.
- Use lead-free solder and a proper torch technique to create robust, sealed connections.
- After installation, gently test for leaks at low pressure before restoring full service.
