This heavy-duty HDPE lid with EPDM gasket provides airtight sealing for 3-1/2, 5, 6, and 7-gallon buckets. Engineered with tamper-evident slots and break-away tabs, the lid ensures contents remain secure and untampered. The recessed design and reinforced ribs enable stable, strong stacking capability. FDA-compliant materials make it ideal for food, chemical, and industrial applications. Features a professional-grade liquid-tight seal when properly installed with a rubber mallet. While reusable, the tamper-evident design clearly shows if the bucket has been previously opened.
