Okay......
Which air hose is this??? Is it one of the little air hoses that connects to the valve cover, or are we talking about the giant intake hose itself, specifically one of nipple connections that is in the front????
If it's one of the small rubber hoses, they should be somewhat soft, but not rediculously brittle. If that's the case, then this is normal... Age & heat will harden the rubber hoses.
Same for the cam cover gaskets (the big rectangular ones & the small round ones that the cover screws go into), they should not be hard & brittle. If that's the case, you'll have oil leaks after awhile.
The rubber items for the cam covers are still available from Toyota. As for the air hoses, it can vary on availability.
