Any glass jar is safe to use for canning purposes. The jar should be submerged in boiling water to disinfect it prior to use. Use new rubber sealing rings always.
There are several purposes of the lid and rim on home canning jars. The 2-piece closure allows air to escape from the jar during processing. The air is pushed out of the jar by steam building up in the jar during the hot water bath method and from pressure in a pressure canner. During the canning process the air escapes under the lid. This is supposed to happen. If improper headspace is left in the jar it can cause liquid to escape from the jar when the air is vented. Check your recipes closely for headspace and measure each jar when filling.
