IF the hose fitting/dump valve has torn from the bladder you are S.O.L. but if it’s just the big inflator hose they are interchangeable between brands except for Oceanic and can be found online in different lenghts.
When changing or inspecting these always make sure there are two cable ties on each end, nothings worse (except maybe OOA) than going to add air to accend and finding the hose is no longer attached to the BC!
