Coach, since I have one let me add for the folks ....it is basically an adapter that allows you to use the style of inflater end that is used to blow up tires....that way e.g. you can stop at a gas station....at least you could in the days they inflated tires....and blow up your tube, pontoon , etc.

Coach, this must mean your air source has the tire inflater type but most sources I know of you can change the type of inflater?????

Sorry, I don't know where to get the replacement...got mine from Cabela's too...what about Netcraft or is it Jann's now?
