Rubbermaid Inc/jarden 1440031050 Dome Canning Lids 12 Pack

Product Description

The RUBBERMAID INC/JARDEN 1440031050 is a 12-pack of Ball Regular Mouth Dome Canning Lids designed for home food preservation. Each lid features a BPA-free patented sealing compound that creates an airtight seal when processed correctly. The dome design provides a visual seal indicator — the lid flexes down when a proper vacuum seal is achieved. These lids are rated for food preservation for up to 1 year when sealed and stored under recommended conditions. They fit standard regular mouth jars with a 70mm opening. Intended for single-use canning applications, they are not recommended for reuse as a primary seal.

These lids are suited for water bath canning and pressure canning of fruits, vegetables, jams, jellies, pickles, and other shelf-stable foods. The 70mm regular mouth sizing is the industry-standard fit for most common home canning jars. The 12-pack format supports single-batch processing runs. Package quantity is listed as 24 units per case for wholesale or bulk purchasing purposes.

Installation Notes

Lids should be inspected before use and discarded if the sealing compound is cracked, nicked, or damaged. Follow current USDA-approved canning guidelines for processing times and temperatures appropriate to the food type and jar size. Do not reuse lids as primary seals, as the sealing compound may not re-form an airtight vacuum on a second processing cycle. Allow jars to cool undisturbed after processing before checking seal integrity.
