Screw-On Caps for Water Cooler/Dispenser Plastic Jugs, 48mm Bottle Lids

The water dispenser bottle caps included in this package are designed to be compatible with a variety of 3 and 5-gallon plastic water dispenser bottles that require twist-on (screw-on) caps. The package includes 3 screw-on caps with a foam liner, offering two different sizes to choose from - 48mm or 53mm.

To determine the appropriate cap size for your water jug, refer to the label on the jug, which will specify the required cap size. Alternatively, you can measure the "T Dimension" at the top of the jug using a caliper or ruler. The 48mm cap will fit jugs with a 48mm (1.89 inches) T Dimension, while the 53mm cap will fit jugs with a 53mm (2.09 inches) T Dimension.

The dimensions of the 48mm cap are as follows: inner diameter (ID) of 48mm (1.89 inches) and outer diameter (OD) of 50mm (1.97 inches). This size cap is compatible with models such as AquaNation, Crystal Spring, Primo (Walmart, Lowe's) bottles with twist caps, New Wave Enviro, and Ore International.

The dimensions of the 53mm cap are: inner diameter (ID) of 53mm (2.09 inches) and outer diameter (OD) of 55mm (2.17 inches). This size cap is compatible with models such as American Maid.

It's important to note that these caps are not suitable for use on water dispenser bottles that require snap-on caps, such as Polar Artic, Nestle PureLife, Primo bottles (with snap-on caps), Ice River, and Glacier. Additionally, these caps are not intended for use on glass jugs.

Please be aware that due to brand-to-brand variations in gallon-sized jugs, including differences in plastic thickness and product design, it can be challenging to determine the appropriate cap size by measuring the "T Dimension" of the jug's neck. Instead, we recommend carefully measuring your own caps to ensure you select the correct size.

The 48mm screw-on caps with foam liner included in this 3-pack are only compatible with plastic water dispenser jugs that have a 48-400 threaded neck finish. 1, 2, 3, and 5-gallon water dispenser jugs frequently use either the 48mm or 53mm cap size, so it's essential to measure the inner diameter of your existing caps to determine the appropriate size for your needs.
