Water Dispenser Valve for 55mm Threaded Bottle Jug, Plastic Gallon Water Bottle Faucet include Lid Dirt Protector

It does not fit the standard Walmart/Kroger 3 gallon or 5 gallon threaded containers. Earlier I bought a 48 mm one which was an under fit and now this 55 mm one which is anover fit. Now I am not sure if there is an interim 52 or 53mm!

This product fit my jugs perfectly and met my expectations. It lasted a couple of years before dripping at all which is what I have seen from similar products. I like that its BPA free.
