Copper Reducer for 2-1/2" to 2" Tube

This wrot-copper reducer connects 2-1/2-inch tube to 2-inch tube using C x C solder joints. It meets ASME/ANSI B 16.22 and carries a 336 psi rating at 100 °F. The fitting suits residential and light-commercial plumbing systems that require a straight size transition.

Installers needing a direct copper step-down

The component fits jobs where a single reducer replaces a bushing and short nipple. It is not for systems that demand press or push-fit connections, nor for lines that exceed the 400 °F upper temperature limit or the 336 psi pressure ceiling.

Handles standard hot and cold distribution

The reducer manages typical potable-water pressures and temperatures up to 400 °F with ample margin. Headroom diminishes in high-rise stacks or process piping where sustained pressure approaches the 336 psi rating or where thermal cycling pushes beyond the listed range.

Questions about this item

What pipe sizes must I already have to connect this 2-1/2" x 2" copper reducer?

You need one tube with a 2-1/2 inch outside diameter and another with a 2 inch outside diameter, both prepared for sweat soldering.

Will the ASME/ANSI B 16.22 rating on this fitting match the older copper pipe already in my system?

Yes, the reducer meets ASME/ANSI B 16.22, the standard covering wrought copper solder-joint fittings used in existing residential and commercial installations.

How can I confirm the joint is sound after soldering the CxC connections?

Pressurise the line up to 336 psi at 100 Degrees F and inspect each soldered joint for leaks; the fitting is rated for that pressure and a temperature range of -20 to 400 Degrees F.
