Application

The Legend Valve 450-639 is a copper coupling with an internal stop dimple designed for 2-1/2 inch inside diameter and 2-5/8 inch outside diameter copper tubing. It creates a permanent solder joint in residential or commercial plumbing systems. The transparent finish allows visual confirmation of solder flow during installation. It suits plumbers and maintenance crews joining straight lengths of Type K, L, or M copper pipe.

Function

The integrated stop dimple centres the fitting automatically so both pipe ends meet at the correct depth without measuring or marking. This reduces the chance of a short insertion that would weaken the joint. The coupling slides over prepared pipe ends and is then soldered using standard copper alloys and flux. No additional brackets, clamps, or sealants are required beyond normal soldering practice.

Compatibility

Verify that the existing tubing is nominal 2-1/2 inch copper with a 2-5/8 inch outside diameter before ordering. Confirm the system pressure and temperature ratings match the coupling’s class for the intended service. Ensure local codes permit soldered copper joints for the application and that the installer has appropriate torch and soldering equipment. This product contains chemicals listed under California Proposition 65.

Questions about this item

Will the internal stop dimple ever need replacement in a 2-1/2" copper line?

The stop dimple is a permanent raised ridge formed inside the copper coupling during manufacture. It does not wear out, corrode separately, or require servicing under normal plumbing conditions.

What limits how long this coupling can handle continuous water flow?

The limiting factor is the copper tube and solder joint rating, not the coupling itself. Properly soldered joints on 2-1/2" Type L or K copper handle continuous flow indefinitely within the tube's pressure and temperature limits.

Does the coupling generate any noise, heat or extra power draw when water runs all day?

No. It is a passive copper fitting with no moving parts, electronics or power connection. It adds no noise, no measurable heat and draws zero power regardless of how long water flows through it.
