Vintage Double Hose

I am signing up for a Nitrox class and If I am going to dive Nitrox regularly then I am going to do so with my PRAM. I sent Bryan a USD DA Aquamaster which he converted. I believe that all the internal rubber parts were rebuilt with modern rubber parts. Is the regulator as it is typically rebuilt compatable with Nitrox? If so to what percent? If not what typially needs to be done to get it Nitrox ready?

Thanks.

In short, no problem. Mine has seen a lot of nitrox.
