Kilner® jars are beloved for their timeless design and reliable airtight seal, but over time the rubber seals can wear out, crack, or lose their elasticity. When that happens, your preserves, dry goods, or ferments may not stay as fresh as they should. Fortunately, replacing the seals is simple and affordable, and this guide will help you find the perfect Kilner® replacement seals for your jars.
Whether you're a seasoned preserver or just starting your Kilner® collection, understanding which seals fit which jars is essential. In this buying guide, we'll cover the different types of Kilner® seals, how to measure your jar, where to buy genuine replacements, and tips to extend the life of your new seals.
Why Kilner® Replacement Seals Matter
The rubber seal is the heart of a Kilner® clip top jar. It creates the airtight barrier that keeps your homemade jams, pickles, and fermented vegetables fresh for months. Over time, exposure to heat, acidic foods, and repeated washing can cause the rubber to harden, crack, or stretch out of shape. A worn seal compromises the vacuum seal, leading to spoilage and wasted effort.
Replacing the seals is a cost-effective way to extend the life of your jars. Instead of buying new jars, you can simply purchase a pack of genuine Kilner® rubber seals and restore your jars to like-new condition. This not only saves money but also reduces waste, aligning with the sustainable ethos of home preserving.
- Check seals regularly for cracks, stickiness, or loss of elasticity.
- Replace seals at least once a year if you use your jars frequently.
- Always use genuine Kilner® seals to ensure a perfect fit and safe preserving.
Understanding Kilner® Seal Sizes and Compatibility
Kilner® jars come in various sizes, and each size requires a specific seal. The most common sizes are for 0.35 litre, 0.5 litre, 1 litre, 1.5 litre, 2 litre, and 3 litre jars. To identify the correct seal, measure the inner diameter of your jar's lid or consult the jar's base for a size indicator. For example, the Kilner® 1 Litre Fermentation Set uses a standard 1 litre seal, while the Square Glass Clip Top Jar - 0.5 Litre requires a smaller seal.

A popular option is the Rubber Seals For 0.35 2 Litre Clip Top Jars - Pack of 6, which covers a range of sizes from 0.35 to 2 litres. This multipack is convenient for households with multiple jar sizes, ensuring you always have a spare seal on hand. For 3 litre jars, you'll need a larger seal specifically designed for that capacity.

- Measure the inner diameter of the lid (in cm) to find the right seal size.
- Check the jar's base or lid for a size stamp (e.g., '1L' or '0.5L').
- When in doubt, refer to the Kilner® official sizing chart or contact customer support.

Step-by-Step Guide to Replacing Your Kilner® Seals
Replacing a Kilner® seal is a quick and easy process. First, remove the old seal from the lid groove. You may need to gently stretch it out; if it's brittle, it might break, which is fine. Clean the lid groove thoroughly to remove any residue or food particles. Then, take your new seal and press it evenly into the groove, ensuring it sits snugly without twisting.
Once the new seal is in place, test it by closing the jar and checking for a tight seal. You can do a simple water test: fill the jar with water, close it, and invert it to see if any leaks. If the seal is correct, no water should escape. This ensures your preserves will stay fresh.
- Soak new seals in warm water for a few minutes to make them more pliable.
- Avoid using sharp objects to remove old seals to prevent scratching the glass.
- After replacing, hand wash the seal with mild soap and dry thoroughly before use.
Tips to Extend the Life of Your Kilner® Seals
To get the most out of your replacement seals, proper care is essential. After each use, remove the seal and wash it separately in warm soapy water. Avoid putting rubber seals in the dishwasher, as high heat and harsh detergents can degrade the rubber. Dry them thoroughly before storing the jar with the seal in place.
Store your jars with the seals slightly loose to prevent compression. Also, keep seals away from direct sunlight and extreme temperatures. With proper care, a Kilner® seal can last for years, ensuring your jars remain airtight and your food stays fresh.
- Hand wash seals only – no dishwasher.
- Store seals in a cool, dry place when not in use.
- Replace seals immediately if they show signs of wear to maintain safety.
Investing in genuine Kilner® replacement seals is a small price to pay for the peace of mind that your homemade preserves, ferments, and dry goods are stored safely. Whether you need a single seal or a multipack, the official Kilner® store has you covered. Check out the Rubber Seals For 0.35 2 Litre Clip Top Jars - Pack of 6 to keep your jars in top condition.
