2½ in Bronze Sweat Union
This bronze sweat union joins two 2 1/2 in copper tubes in potable water systems. Rated for 269 psi and 200 Degrees F, it meets ASME B 16.18, ISO 9001, NSF/ANSI 61 and NSF/ANSI 372. The straight union design allows straightforward assembly and disassembly for maintenance.
Potable water installers and service technicians
Installers needing threaded, press or push-fit connections should select a different fitting type. Systems requiring a higher pressure or temperature rating than 269 psi and 200 Degrees F will need alternative components.
269 psi maximum operating pressure
This pressure limit defines the safe working range for the union in the intended potable water application. Verify that the system design pressure does not exceed this value before installation.

Questions about this item
What copper tube size must the existing pipes be for the 2 1/2 in sweat union to fit?
Both pipe ends must be 2 1/2 in copper tube size, which corresponds to a 2 5/8 in outer diameter, so the union slides onto matching tubing before soldering.
Will the bronze union meet the same lead-free and potable-water standards as older copper fittings already in the system?
Yes, it complies with NSF/ANSI 61 and NSF/ANSI 372 for lead-free potable water use, matching the requirements that govern modern copper plumbing components.
After soldering, what pressure and temperature limits confirm the joint is holding as designed?
The union is rated for 269 psi maximum operating pressure and 200 °F maximum operating temperature; staying within those limits indicates the assembly is performing to its ASME B16.18 rating.
