MYLOLF 3 & 5 Gallon Water Jug Cap, Reusable Food Grade Silicone Replacement Cap for 55mm Standard/Screw/Crown Tops Water Bottle and Water Dispensers, Non-Spill & Leak Free - 12PCS

These worked great on our bottles. They held up from leaking even when the bottles fell over in the car. Very happy with these. They fit tightly.

¡Estos tapones de goma para botellas de agua son fantásticos! Se ajustan perfectamente, creando un sello seguro que evita fugas y nos permite usar el dispensador de agua sin problemas. Son flexibles y duraderos, por lo que es fácil cambiarlos entre botellas sin desgaste. ¡Además, son muy fáciles de limpiar!

Perfect fit, saves wasting left over water when you remove the vender cap.

Okay

I recently switched from having my home water delivered to taking the 5 gallon jugs to a water filling station myself. This helps save quite a bit of money! I kept the 5 gallon jugs from my former water delivery service and had to remove the thick, clear plastic ring that they had on the bottles in order to get these silicone covers to fit. This is fine by me because it makes the mouth of the jug a bit larger and easier to fill. I just stretch the silicone cap over top when it’s full and it seals perfectly. I haven’t tipped the jugs completely upside down, but I have briefly laid them in their side and there was no leakage at all. There is a little stopper in the middle of the cap that pops inward if you are using a top loading water dispenser so there isn’t any spillage. I use an electric pump with a tube that goes down inside of the jug and it just sits nicely over the cap. I have already save a good amount money by using these to refill my own jugs. They have already paid themselves off. So far they have lasted a couple of months with no signs of decreased quality. If they ever do wear out I will buy more though.
