you can get a regulator from ebay...just search for a nitrogen purging regulator i got my smith regulator for $42 new w/ 450psi delivery psi. Then you need a fitting to connect it to an expansion tank and this can be done with a 1/4"npt 1/2" pipe fitting other then that go to welding supply and they also sell bottle mounts which are nice for the bottle mount.
