Heater core by pass valve

[1968340S]

I have the original H valve. I have just a small amount of leakage in the by pass position.
Ok to use or time to get a new one. Can't seem to locate any made in copper, all aluminum.

Unless you're trying to stay 100% original, I don't see a problem with aluminum

There is a guy in Wisconsin that has NOS and other versions.... Can't remember his name, he does not have a big web presence.... Call Bob at GlenRay and ask him. Bob gave me the contact info when I rebuilt my box and he recored my heater.
