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

The dimensions of the 53mm cap are as follows: inner diameter is 53mm (2.09 inches) and outer diameter is 55mm (2.17 inches). This cap is specifically designed for models such as American Maid. It's important to note that these caps are not universal, as there are various cap sizes available to accommodate 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 closure type (screw-on or snap-on). For example, the 53mm sized screw-on cap is suitable for 1, 2, 3, and 5 gallon American Maid brand bottles. The 48mm sized screw-on cap, on the other hand, is generally suitable for 1, 2, 3, and 5 gallon Bluewave, New Wave Enviro, PureAqua, H8O, and LavoHome brand bottles. However, these caps do not fit on bottles that require Snap-On caps, such as Nestle, Primo, Zephyrhills, and several other brands.

The 53mm (53-400) size screw-on caps with foam liner included in the 3-pack are compatible with American Maid plastic water bottles and water jugs with a 53-400 threaded neck finish. These caps are not compatible with water jug brands like Bluewave, New Wave Enviro, PureAqua, and Ore International, which require a 48mm sized cap. They also are not suitable for water dispenser bottles that require snap-on caps, or for use on glass jugs.

The caps feature a 3-ply compressible foam liner, are BPA free, and are made in the USA. It's important to note that the cap is not designed to be leakproof.

Cap size cannot be determined solely from the jug’s brand, as some brands have changed their bottle designs over the years. Additionally, the jug's gallon size does not determine the cap size, and it is essential to measure the outer diameter of the old caps to find the right cap size for your bottle. The 53mm size caps have an outer diameter of about 2-3/16”, or you may also check the water jug's label to find the specified cap size.

It's emphasized that water bottle caps are not universal, and measuring is key to finding the right cap size for your specific bottle.
