5 Gallon White Bucket & Gamma Seal Lid - Food Grade Plastic Pail & Gamma2 Screw Seal Tight Lid (Red)

A Gamma Seal lid adapts the bucket to a threaded spin-on spin-off lid. A rubber mallet (not included) is useful for installing the threaded ring to the bucket. The ring seals to the rim of the bucket with an O-ring gasket. The threaded lid portion then spins on and off sealing to the ring with another O-ring gasket. The O-ring gasket has a food grade silicone lubricant the helps the O-ring not to grab the plastic sealing surfaces. If this lubricant is removed through excessive cleaning, the O-ring can grab and stretch and loose it's retention to the lid. Plastic containers are rarely. Leaving the lid snug for a period and allowing the several components to to each other in a warmer room temperature environment can help with performance. For long term food and liquid applications we recommend a conventional snap-on lid with a gasket. The Gamma Seal shins in it's convenience. We like the Gamma Seal for applications requiring convenient frequent access.
