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

The 53mm-size cap has an inner diameter of 53mm (2.09 inches) and an outer diameter of 55mm (2.17 inches). These caps are designed for use on models such as the American Maid brand. It's important to note that these caps are not universal, as there are many other cap sizes available for different water bottle brands.

Each water bottle brand has its own unique neck design, which requires a specific cap size based on the width of the neck and the closure type (screw-on or snap-on). For instance, the 53mm-sized screw-on cap fits the 1, 2, 3, and 5-gallon American Maid brand bottles, while the 48mm-sized screw-on cap generally fits the 1, 2, 3, and 5-gallon Bluewave, New Wave Enviro, PureAqua, H8O, and LavoHome brand bottles.

These caps do not fit on bottles that require snap-on caps, where the bottle's lip is rounded and has no thread. 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. Additionally, these caps are not compatible with glass bottles.

The 53mm (53-400) size screw-on caps with a foam liner are compatible with American Maid plastic water bottles and water jugs that have a 53-400 threaded neck finish. These caps are not compatible with water jug brands such as Bluewave, New Wave Enviro, PureAqua Jugs, and Ore International, which require a 48mm-sized cap.

The caps feature a 3-ply compressible foam liner and are BPA-free, made in the USA. It's important to note that the cap is not designed to be leakproof. The cap dimensions are an inner diameter of 53mm (about 2-1/8") and an outer diameter of 55mm (about 2-3/16").

Determining the right cap size for your water bottle can be challenging, as some brands have changed their bottle design over the years, and the jug's gallon size does not determine the cap size. The easiest and most reliable method is to measure the outer diameter of your old caps. The 53mm size caps have an OD of about 2-3/16". Alternatively, you can check the water jug's label, as it may specify the required cap size.

In conclusion, it is crucial to measure, measure, and measure again to ensure you get the right cap size for your water bottle, as water bottle caps are not universal.
