Threaded Screw-On Caps for 3 and 5 Gallon Water Bottles (3 Pack, 53mm, White)

Cap size dimensions for a 53mm cap are as follows: Inner Diameter - 53mm (2.09 inches), Outer Diameter - 55mm (2.17 inches). This size cap is specifically designed for use on models like American Maid. However, it is important to note that these caps are not universal, as there are various other cap sizes available in the market.

Each water bottle brand has its own unique neck design, which means that a specific cap size is required based on the neck width and closure type (screw-on or snap-on). For instance, a 53mm sized screw-on cap is suitable for 1, 2, 3, and 5 gallon American Maid bottles. On the other hand, a 48mm sized screw-on cap generally fits 1, 2, 3, and 5 gallon Bluewave, New Wave Enviro, PureAqua, H8O, and LavoHome bottles. It is important to note that these caps are not compatible with bottles that require Snap-On caps.

Brands that typically require Snap-On caps include Nestle, Primo, Zephyrhills, Crystal Springs, Poland Spring, Arrowhead, Deer Park, Ozarka, Pure Life, Brio, Polar Arctic, and Clack. It is worth mentioning that these caps are not suitable for glass bottles.

The 53-400 threaded neck finish makes these caps compatible with American Maid plastic water bottles. Each pack includes 3-pk of 53mm (53-400) size screw-on caps with foam liners.

However, it is essential to mention that these caps are not compatible with water jug brands like Bluewave, New Wave Enviro, PureAqua Jugs, and Ore International, which require a 48mm sized cap. Moreover, these caps should not be used on water dispenser bottles that require snap-on caps or glass jugs.

The caps are equipped with a 3-ply compressible foam liner, ensuring they are BPA free. Made in the USA, the caps are not designed to be leakproof. Remember, determining the right cap size can be challenging, as some brands have changed their bottle designs over the years, and the gallon size does not necessarily indicate the cap size.

To find the correct cap size for your bottle, simply measure the OD (outer diameter) of your current caps. The OD for 53mm size caps is approximately 2-3/16”. Alternatively, check the label on your water jug, as it may specify the required cap size.

In conclusion, always remember to measure the cap size accurately as water bottle caps are not one-size-fits-all!
