Which Jars are Safe for Pressure Canning?

Pressure canning is the only method recommended safe by the U.S.D.A. for preserving low-acid foods such as meats and fish, soups & stocks. Wondering what the difference is between water bath canning and pressure canning? It’s all about the temperature!

A boiling water bath canner cannot surpass 212 degrees Fahrenheit. A Pressure Canner brings jar temperatures up to 240-250 degrees Fahrenheit. This temperature can be reached only by creating steam under pressure. At this temperature we can be assured that 100% of bacteria is killed.

In a recent post we talked a bit about pressure canners vs. pressure cookers and some of the guidelines that the National Center for Home Food Preservation recommends for safe pressure canning. In addition to choosing the proper canning method, it’s also very important to use jars and lids that are safe for pressure canning.

The entire line of glass Ball jars and Orchard Road jars* have been designed, tested and approved for pressure canning. The metal 2 piece lids that accompany these jars are also approved for pressure canning for home canners by the National Center for Home Food Preservation. Our 1-Piece Hi-Heat Metal Canning Lids are designed for pressure canning, but they haven’t yet been approved by the NCHFP for the home canner.

*Orchard Road jars have been discontinued. There’s a limited supply available. Orchard Road will continue to produce 2 piece metal lids, which are also approved for pressure canning.

If you already have jars but need lids, our bulk canning lids have the same formulation as Ball’s lids. So, if you’re doing large quantities and already have the jars, our bulk wide mouth & regular mouth lids are a practical option – regular mouth lids are available in gold and silver.

New to Pressure Canning?

If you are new to pressure canning we encourage you to read this article from NCHFP about how to get started with pressure canning.

Pressure canning provides an opportunity to preserve many things that cannot be safely canned in a water bath canner including, meats, meat stocks, and more. Here are some guidelines and recipes from the National Center for Home Food Preservation.

    Do you have any jars that are like your barbeque sauce jars that are safe for pressure canning?

    Like taller/skinnier ones with shoulders?

      Hello Erin, The short answer is no.
      We’re not aware that a jar/lid designed for that exists….or we’d carry it. 🙂
      The nerdy answer: Since pressure canning also requires a firmer plastisol; like that found in the 2-piece canning lids and our Hi-Heat regular mouth (70mm CT) and Hi-Heat wide mouth (86mm CT) lids. While we do have some customers who use some of our economy jars (along with the Hi-Heat lids) for pressure canning, those jars haven’t been tested and cleared for pressure canning. We wouldn’t recommend trying the bbq style bottles in the pressure canner mostly related to the physics that happens during processing. The shape of the jar and the venting ratio (volume of the jar & radius of the area that would allow venting) is quite different and may be problematic.

    We came across some older Ball freezer jars, would it be safe to changenout the kids for pressure canning and use the glass freezer jars?

      Hi Jaimi,
      While we like to encourage responsible re-use of jars, we cannot recommend that you use jars of an unknown standard in your canning process. Many jars are not designed to withstand the pressure canner process and you may end up with product loss or suffer personal injury. Ball jars are approved for pressure canning, however you mentioned these jars were older. Do you know the age of the jars?

    Would this method be acceptable for peanut butter and almond butter?

      Hi Shannon,
      Fresh homemade peanut butter is best stored in the refrigerator or freezer. We encourage you to reach out to your local Extension office and speak with a Master Food preserver to discuss your specific recipe.

      Hi Shirley,
      If you are pressure canning, it is important to select jars and lids that have been designed and manufactured with pressure canning in mind. The entire line of glass Ball jars with lids and Orchard Road jars and lids have been tested at the higher temperatures inherent with pressure canning. Contact us if you have further questions.

    I bought some spaghetti sauce in a jar that said Mason on the side. Is this safe to use for canning?

      Hi Deb,
      While the jars that say Mason may be usable with regular mouth lids. We cannot speak to the integrity of the glass once it has already been heated and cooled and used. For this reason we cannot say that it is considered safe for canning. However, it could certainly be used for other uses.
