Pressure Balance Loop

I need to create a pressure balance loop. The diagrams I've seen show a 4 way tee to start the loop (supply line, then left, right, straight through the loop).

Does anyone know if that 4 way 1/2 copper coupler exists? I can't seem to find it? Or is there a special name?

The 4 is the 4 way copper coupler, and the rest is a crude loop!
Thanks in advance!!!

Yep Revere copper has em, called a cross. You might get one at the local plumbing supply (not lowes or hd, a real plumbing supply house) you may have to special order it.

Pressure balance loops are an exercise in futility. I never install them unless the heads are great distances apart, and then I run separate pipes from the valve to the two ends.
