Hufopik Threaded/Screw-On Caps for 3 and 5 Gallon Water Bottle Jugs (6 pk) (53mm, White)

Features

• Compatible with American Maid plastic water bottles and water jugs that have a 53-400 threaded neck finish. Included: 53mm (53-400) size screw-on caps with foam liner.
• Not for use on water dispenser bottles that require snap on caps; not for use on glass jugs.
• Caps feature a 3-ply compressible foam liner. BPA free. Cap is not designed to be leakproof. Cap Dimensions: Inner Diameter: 53mm (about 2-1/8"); Outer Diameter: 55mm (about 2-3/16")
• Note: it is difficult to determine the cap size from the jug’s brand, as some have changed their bottle design over the years. And the jug's gallon size does not determine the cap size.
• To find the right cap size for your bottle, the easiest and most reliable method is to simply measure the OD (outer diameter) of your old caps. The 53mm size caps have an OD of about 2-3/16”. Or, check the water jug's label, as it may also specify which cap size is needed.
