Frequently Asked Questions

​How can I tell when my can of Fix-a-Flat was manufactured?

The current product date stamp on your yellow can should look like this: 17312 AT 0054

  • The first 2 digits tell you the year that the product was manufactured (2017)
  • The next 3 digits tell you the day of the year that the product was manufactured (the 312th day of the year)
  • The next set of letters and numbers is batch code information for internal use

In this case, the date of manufacture November 7, 2017. The can would be good until November of 2019. If the number stamped onto the bottom does not follow this format, the product was manufactured prior to 2011.
