Tattler Reusable Canning Lids and Rubber Rings - a Product Review

Lid lifting test for seal
This summer of 2011 was quite a canning experience for me. For one thing, I have completed the basic necessary tool set for canning, as I have purchased a pressure canner, Presto, which has enabled me to try to can ANYTHING.  I still used the boiling water bath (BWB) canner where applicable.  After telling my husband that I am now really getting into canning, his eyes lit up, and ordered a pallete of 900 quart jars (that was not a typo, it was really 900 jars) and two bulk boxes of Tattler reusable canning lids and rubber rings (that's a total of 576).

Seeing this summer of abundant produce as an opportunity to test how good these reusable lids and
rubber rings are, I used them, opened some jars, and reused them. I used them both in BWB and in pressure canners.  My observations are as follows:

1) Those processed using BWB, the lids were easy-peasy.
2) Those processed using pressure canner, I had varying results. Probably depending on the viscosity of the liquid, or the headspace, or how tight or how loose I closed the bands...sigh...some sealed and popped in okay. Some did not seal at all (probably boil overs are responsible so I needed to increase the headspace on reprocessing), some sealed but lids did not pop in (questionable complete removal of air).
3) In some reused lids, they did fine still. But I recently found a jar that I canned that seemed to seal but the lid remained popped up, which, to my dismay, remained popped up after opening and washing. You see, I thought the reason it was popped up prior to opening despite a good seal was that I tightened too much that the air had a hard time escaping, so that the increase in temp and volume only pushed the lid up more than it pushed the air out through the rubber ring.  I expected the lid to get back to its original shape after pressure equilibrium is achieved upon opening the jar. It did not.

Now I am thinking, if I reuse this particular lid, I would not have the popping in of lid as a visual cue that the processing created a vacuum (removal of air is a key factor that is responsible in keeping the quality of the canned food. Vacuum is lack of air. Vacuum is created by pushing the air in the headspace out during the increase in temperature, either by BWB or pressure canner.  Lowering temp then contracts the volume, so the vacuum created sucks in the lid, and seals the jar.) I do not know if vacuum produced in processing will have enough strength to suck in this popped up lid if I reuse it.  The only gauge I will have will be the lid-lift test 24-48 hrs after processing.

Well, there really is no other option for reusable canning lids/rubber rings, I guess, and I still have several hundreds of unused reusable lids/rings that I am stuck with.  Other than that freaky lid, it seems that most users are completely satisfied (although I know that the survivalblog author spent some time getting used to the Tattler lids as he also had varying degrees of unsuccessful outcomes like I had). Maybe with practice I will get better in time.


  1. Great post – I’m going to Tweet about your blog.

  2. Manang,

    Great blog. You obviously put a great deal of time and effort into it. I would like to briefly adddress your specific problem, which can be easily solved.

    This summer (2011) we adjusted our instructions in an effort to eliminate overtightening of the metal band prior to processing. If the metal band is too tight during processing, pressure will be captured to the point it will cause lids to bulge and potentially affect the seal during cooling.

    We have found the best method for applying the metal band is to turn it until only finger-tip tight. This will allow pressure to sufficiently release during processing, which will subsequently ensure the optimal seal when the cooling effect creates vacuum.

    A youtube video of this procedure can be seen at the following link.


  3. Thank you for your articles
