Kerr 2139400 Wide Mouth Mason Jar Half Pint 12 Pack

Product Description

The Kerr 2139400 is a half-pint wide mouth mason jar sold in a 12-pack with two-piece closures included. Each jar is designed for home canning and food preservation, accepting standard wide mouth lids and bands for a reliable seal. The wide mouth opening simplifies filling, cleaning, and removing solid or thick contents. At 6 pounds for the case, these jars are a straightforward supply item for kitchens, homesteads, and small food operations that process product in quantity.

These jars are suited for preserving fruits, jams, jellies, spreads, meats, and fish through both heat processing and freezer storage. The half-pint size works well for small-batch preserves, portion-controlled condiments, and single-serve packed items. They are a common staple for residential canners and small commercial prep operations that require consistent jar sizing across multiple batches.

Installation Notes

Inspect each jar for chips or cracks before use, as damaged jars can fail under heat processing. Always follow current USDA or National Center for Home Food Preservation guidelines for safe canning procedures and processing times. Do not reuse one-piece commercial lids; use the included two-piece closures for a proper seal. Allow jars to cool undisturbed on a flat surface after processing before checking for seal confirmation.
