To prevent spoilage, your equipment must be in good shape and working properly:

 Have the pressure gauge and seal on your pressure canner tested every year for accuracy. (Weighted gauges don’t require testing.) This service is often offered for free at your local cooperative extension office.

 Use jars and two-piece caps that are made for home-canning. Discard any jars that are cracked or nicked.

 Never use single-use sealing lids a second time. Always use new lids. The sealant on the underside of the lid is good for only one processing. If your jars do not seal the first time, always replace the lid with a fresh one. There may be a problem with the sealant, despite starting with a new lid.

 Check the rubber gasket on reusable lids for signs of wear. With proper care, gaskets can be reused up to eight times before needing to be replaced, depending on whether you are pressure canning or water-bath canning.
