Query: Replacement Parts Problem

The marinater worked will until the rubber seal stretched and would no longer seal the top to the base......and I have just spent at least 30 minutes on AMAZON and still have no source for replacement of the seal.......I think that AMAZON should also consider this when they are setting up sales for items. Many require replacement parts to continue functioning....and this is certainly true of the VacU vin products....If the seal does not fit well, the vacuume will not hold......
