The Airscape Bucket Lid Insert is the ultimate bulk storage solution. Designed to fit snugly inside standard 5-gallon buckets or any bucket with an 11.9 diameter, this insert maximizes storage capacity while ensuring maximum freshness. It's ideal for storing large amounts of coffee, BBQ pellets, pet food storage, and more. It integrates a Fresh-port valve that allows bucket contents to be flushed with argon gas to make these pet products even better for preserving the goods' life and a degassing lid to self-burp and release any carbon dioxide buildup. Note: This product is the insert only - bucket not included.
