Legend Valve 450-447 Reducing Coupling

This Legend Valve fitting is a 4" x 2" copper reducing coupling with a Ftg x C connection. It joins a 4-inch fitting end to a 2-inch copper pipe end in plumbing systems. The component is supplied new and carries California Proposition 65 warnings for chemicals known to cause cancer and reproductive harm. It serves as a transition piece in water supply or heating installations.

Suited for copper pipe transitions

Installers reducing a 4-inch fitting down to a 2-inch copper pipe will find this coupling matches that exact requirement. The Ftg x C design means one end slips into a fitting while the other accepts a pipe, so it cannot connect two pipes directly. Builders needing a C x C coupling or a different size reduction must select an alternative fitting type.

Handles 4-inch to 2-inch copper reduction

The coupling comfortably bridges the specified diameter change in standard copper plumbing layouts. Its transparent finish allows visual confirmation of the joint during assembly. The fitting reaches its limit when the system demands a different connection style, such as press-fit or threaded ends, or when the pipe material is not copper.

Questions about this item

What copper pipe sizes must I already have to connect this 4" x 2" reducing coupling?

You need one length of 4-1/8" OD copper tube and one length of 2-1/8" OD copper tube; the fitting slips over the larger tube and the smaller tube inserts into the reduced end.

Will this coupling join directly to existing copper pipe without an extra adapter?

Yes, the Ftg x C design lets the 4" fitting end slide over 4-1/8" OD pipe while the 2" copper end accepts 2-1/8" OD pipe, so no separate adapter is required.

How can I verify the joint is sound after soldering?

Pressurise the line and inspect the solder fillet around both hubs; a continuous, shiny ring with no gaps or pinholes shows the coupling is sealed and working.
