BPA-Free Food-Grade Gamma Seal Lid for 3.5, 5, & 7 Gallon Buckets - 1 Count
Frequently Bought Together
NOTE - Gamma lids may be difficult to install by hand as they require significant pressure to fully seal. We recommend using a rubber mallet to ensure a proper installation for the tightest seal.
TURN ORDINARY BUCKETS INTO AIRTIGHT STORAGE
This BPA-free, food-grade Gamma Seal Lid instantly converts any standard 3.5-, 5-, or 7-gallon bucket into a reliable, airtight container. The two-piece design snaps onto the rim of your bucket, then seals with a simple twist, giving you quick access without wrestling with traditional pry-off lids.
Molded from durable, FDA-compliant HDPE, the lid features a heavy-duty gasket that locks out moisture, pests, and odors—keeping dry goods, liquids, and emergency supplies fresher for longer. Reusable and easy to clean, it’s the smart way to protect pet food, grain, brewing ingredients, or camping provisions.
Just snap the adapter ring in place once, then twist the threaded lid on or off as needed—fast, finger-friendly access every time.

PRODUCT FEATURES
Will this Gamma Seal lid fit the standard 5-gallon buckets I already have?
Yes. The Gamma Seal lid’s outer ring is sized for most 3.5, 5, and 7 gallon buckets with a nominal 12" (30.5 cm) opening, so it snaps onto the vast majority of food-grade and hardware-store pails on the market.
Is the plastic used in this Gamma Seal lid food-safe and BPA-free?
Absolutely. The lid is molded from #2 HDPE that is certified food-grade and completely BPA-free, making it suitable for long-term storage of grains, dry goods, pet food, and other consumables.
Does the lid provide an airtight and watertight seal for long-term storage?
Yes. The threaded inner lid compresses an EPDM rubber gasket against the bucket rim, creating a tight seal that keeps moisture, pests, and odors out while locking freshness in.
How do I install the Gamma Seal lid onto my bucket?
Installation takes only a minute: tap the outer ring evenly onto the bucket with a soft-face mallet until it fully seats, then screw the inner lid into the ring. After the first install, the lid opens and closes by hand like a giant jar top.
Can I use this lid for dry goods such as rice, flour, or freeze-dried foods?
Definitely. The airtight seal and food-safe construction make it ideal for bulk staples, emergency rations, brewing ingredients, and other dry commodities that need protection from air and humidity.
Is the lid sturdy enough for frequent opening and closing?
Yes. The heavy-duty HDPE threading is designed for thousands of cycles, and the replaceable gasket maintains its elasticity even after repeated use, making it perfect for daily access items like pet kibble or snack mixes.
Does this listing include the bucket as well?
No. This product is for one (1) Gamma Seal lid only; buckets are shown for illustrative purposes and are sold separately.
Can this Gamma Seal lid be used for outdoor or garage storage?
Yes. Its UV-resistant HDPE construction and watertight seal protect contents from dust, rain, and pests, making it suitable for camping supplies, garden amendments, or hardware stored in sheds and garages.
