Northern Brewer Grolsch Gaskets

These gaskets are specifically designed as direct replacements for EZ cap swing-top bottles. While they may fit other standard swing-top styles, they are optimized for the EZ cap design to ensure a proper seal.

You should inspect your gaskets before every bottling session. If you notice any cracking, flattening, or if the seal feels loose when you flip the top, it is time to replace them to prevent leaks and carbonation loss.

Yes, always sanitize your gaskets before they come into contact with your beer or fermented beverages. Treat them just like you would your bottles or caps to ensure your brew stays contamination-free.

If your bottles are leaking, a fresh gasket is often the easiest fix. Replacing a worn or dried-out gasket usually restores the airtight seal necessary to hold carbonation.

The 25-count pack is ideal if you brew in smaller batches or only need to replace gaskets on a few bottles. If you are a frequent brewer or have a large collection of swing-top bottles, the 100-count pack is more cost-effective and ensures you always have spares on hand.
