Legend Valve 450-545 Reducing Coupling

The Legend Valve 450-545 is a copper reducing coupling designed to join two different pipe diameters in a plumbing system. It features a 2" x 3/4" inside diameter and a 2-1/8" x 7/8" outside diameter with a C x C sweat connection. The transparent red component is supplied new for residential or commercial bathware installations.

Suitable for standard copper pipe transitions

This fitting suits plumbers and DIYers joining 2-inch and 3/4-inch copper pipes using sweat soldering techniques. It is not for installers who require threaded, compression, or push-fit connections. Buyers needing a straight coupling, a different size reduction, or a fitting approved for potable water without Proposition 65 chemicals should look elsewhere.

Verify pipe sizes and local codes before ordering

Confirm that your existing copper pipes match the 2" and 3/4" inside diameters and that you have the tools and skill for sweat soldering. Check local plumbing codes for any restrictions on fittings carrying California Proposition 65 warnings for cancer and reproductive harm. Ensure the 2-1/8" x 7/8" outside dimensions fit within your available installation space.

Questions about this item

What copper pipe sizes must I already have to join with this 2" x 3/4" reducing coupling?

You need one length of 2-inch copper pipe and one length of 3/4-inch copper pipe; both slide into the solder-cup ends of the fitting.

Can I sweat this coupling onto existing copper lines that have been in the wall for years?

Yes, clean the old pipe ends with emery cloth, apply flux, slide the coupling on and solder — the C x C design works with any clean copper tube.

How do I confirm the joint is sound after soldering?

Pressurise the system and watch for drips; a properly sweated joint shows a continuous fillet of solder all round both cups with no pinholes.
