FAQ

Q:  Are the rubber gaskets reusable, and how long will they last?
A:  Yes, the rubber gaskets are reusable and will seal numerous times when used as directed.  We have received letters from customers stating they have used the lids and rings for as many as 20 years until the rings finally stretched beyond use. That anecdotal evidence is backed up by our own research.  Last summer (2010) we conducted a test using 14 lids and rings. The test materials were product we found in storage since 1976. They were used in both water bath and pressure canning tests over several weeks, during which time all were reused 14 times without failure. The 14th round was conducted on food items, most of which remain in storage awaiting use.  We ended the test due to time constraints.  When cared for properly, many years of use may be expected.   The picture below shows a lid/ring combination that we have sealed 10 times.

Q:  Is there any Bisphenol A (BPA) or phthalates in Tattler Reusable Canning Lids?
A:  NO!  The material we use is an FDA and USDA food grade plastic approved for direct contact use in food applications.  The same is true for the reusable rubber gaskets.

Q:  How do I know if the jars are sealed?
A:  You can tell a lid has sealed properly by lifting gently on the lid after the jars have cooled.   After cooled, remove the metal screw band and gently lift on the lid.  If a failure occured for any reason, the lid will lift off without any difficulty. 

Q:  Can Tattler lids be used in a pressure canner?
A:  Yes.  Tattler lids will withstand any standard, acceptable, home canning process.

Q:  Is a metal seal ring required?
A:  Yes, a standard metal ring is required, the same as with conventional metal lids.

Q:  Can I use Tattler lids on Ball, Jarden, or Leifheit jars?
A:  Yes.  Tattler Reusable Canning Lids can be used on all mason type canning jars where conventional metal lids are commonly used.
