Water bottle lids

[cravenbiker]

Hi All
Does anyone know if you can get an airlock for one of the bottles that you put on top[ of an office style water dispenser/cooler?
I think they are 18.5 Ltr bottles.

Thank you

Stoppers come in all sorts of sizes. Just measure the top of your bottle and buy one at your LHBS or online to fit it. Here's a chart I found.
