Scubapro does and so does Huish (with Atomic, Hollis, Oceanic, Stahlsac, Baresports and Zeagle).
Nope to Scubapro, not in the US at least. Also, Huish doesn't sell tanks and valves in the US. Plus Huish isn't really a brand. They are a parent company that owns many brands. I doubt that is in the spirit of the OPs question. I can't really go out a buy Huish anything.
