That's the sort of question you need to call the store and ask.
I wouldn't be purchasing a used heater core hose. Automotive supply shops sell such hoses in bulk. Just take your old hose in and have them cut you the length that you want. Putting an old hose on makes no sense.
Napa has a really good app that will give you the price, availability , fitment to your vehicles and you can reserve the part if they have it.
Check if Napa Auto offers warranty on their parts?
Cheaper than you would think and a better quality than you would get at the small automotive stores
