These 38mm Poly Seal Screw Caps fit our 1/2 & 1 gallon jugs that we carry. The poly cap will not rust over time. Bag of 12 caps.
We really like these compared to the metal lids. They seal tight and are easy to clean! Definitely worth it!
38mm Poly Seal Screw Caps- 12 ct
These fit my growlers beautifully, but they don't fit the 1-gallon glass apple juice jugs I bought at Whole Foods. I may have to find a solid stopper to seal these jugs instead?
