Learn when and how to swap in Kilner® replacement preserve bottle seals for a reliable airtight seal on your homemade jams, chutneys, and pickles.
Quick Answer
To use Kilner® replacement preserve bottle seals, remove the old seal, clean the bottle rim, press the new seal into place, and test the seal before storing your preserves.
Why Replace the Seal?
Over time, the rubber seal on your Kilner® preserve bottle can lose its flexibility, leading to a weak seal that lets air in and spoils your homemade jams, chutneys, and pickles. Replacing the seal restores the airtight closure, keeping your preserves fresh for longer.
Kilner® replacement preserve bottle seals are designed to fit Kilner® preserve bottles, so you can be confident of a proper fit. Each pack contains 12 seals, giving you spares for multiple batches throughout the preserving season.
When to Replace the Seal
Check the seal before every use. If it feels hard, cracked, or no longer springs back when pressed, it's time to replace it. Also replace the seal if you notice any leaks or if the lid doesn't close as snugly as before.
It's a good idea to keep a pack of replacement seals on hand so you're never caught without one when you're ready to bottle a fresh batch.
Step-by-Step Guide to Replacing Your Kilner® Preserve Bottle Seal
- Remove the old seal: Unscrew the lid and gently pull the old rubber seal out from the groove. If it's stuck, use a soft tool like a butter knife to ease it out without scratching the glass. Check the old seal for cracks or hardening—this tells you why replacement was needed.
- Clean the bottle rim and lid: Wash the bottle rim and the lid in warm soapy water, rinse thoroughly, and dry completely. Any residue or moisture can prevent the new seal from seating properly. Ensure the surfaces are bone-dry before fitting the new seal.
- Fit the new seal: Press the new Kilner® replacement seal evenly into the groove in the lid, starting at one point and working your way around. Make sure it sits flat and isn't twisted. Run a finger around the seal to confirm it's fully seated and flush with the lid.
- Test the seal: Close the bottle and press down on the lid to feel the resistance. For a quick check, fill the bottle with water, close it, and invert it over a sink to see if any water escapes. If water leaks, reseat the seal or check for debris before filling with preserves.
