Product Description
  • Leak-Proof, Food-Safe Solution: When we decided to invent this product, we were trying to solve two common problems with Mason jar lids: either they leak (like the plastic Ball lids), or they are not food safe (like many decorative lids).These simple silicone discs solve both problems by creating a tight seal and ensuring only food-grade silicone touches your jar’s contents.
  • Works with most Mason jar lids: They fit inside most Mason jar lids to make them airtight and leakproof. They work especially well with Ball plastic storage caps, MJL plastic and stainless steel lids, and most of our decorative lids. Each insert has a grooved edge for a secure fit and a small tab for easy removal.
  • Secure & Easy to Use: The grooved edges provide a snug fit inside the lid, and the small built-in tab allows for easy removal.
  • Multi-Purpose Use: Can also be used as fermentation lids. Simply poke a small hole to allow pressure to release, similar to more expensive airlock systems.
  • Eco-Friendly Material: Silicone is a safe, green, non-plastic (BPA free) material that does not leach any chemicals like plastic can. This is the most expensive and highest quality silicone available. LFGB silicone passes the pinch test - they do not turn white if pinched/twisted.

Sizes:

  • Regular Mouth: 70 mm diameter, 2.7 mm thick

  • Wide Mouth: 86.5 mm diameter, 3.3 mm thick

The inserts stay in place even when the jar is upside down. Because silicone is flexible, they may also work with other lids, even if the size isn’t exact. However, not all lids are compatible. We’ve noted compatible options on our website. If the insert feels slightly too large, you can trim it with scissors. This will not affect its performance.

Usage Tips:

  • With a lid and band, place the tab facing down into the jar

  • With a band only, place the tab facing up

  • Some lids seal better when flipped upside down. You can trim off the tab if needed

Common Uses:

  • Fermentation lid (with a pinhole)

  • Microwave splash guard

  • Replacement for rusted flat lids

  • Make lids airtight and leakproof.

  • Prevent food from touching plastic or tin,

  • Line decorative lids for candies or food.

Note: Silicone may sometimes absorb odors. Leaving the inserts in direct sunlight for a few hours will help remove any lingering smells.

I am an avid tea drinker

I am an avid tea drinker. I only drink spring water and 3 different teas. I brew it my self for 18 hours. The silicon seals with glass mason jars is ideal and better than the standard metal lids with a preformed smaller seal. Plus I like the fact that they come out, can be cleaned and replaced when necessary. The stainless steal lids are great. In the past I used plastic jars and plastic lids. I am glad I switched ! DGR.

The BEST option for mushroom storage - who knew?!

I love to add white mushrooms to all my salads, so I like to buy them in larger quantities, even though they can easily turn bad after just a few days. However, after taking my mason jars to the co-op and stocking up on mushrooms, I used a silicone lid liner and metal band to seal it the jar. After taking that home and sticking it in my fridge, I discover a few days later that it seems to be the best option for storing them and for longevity of the mushrooms—who knew?!

I've tried so many methods of storing mushrooms (linen bags, etc.) but they either get brown and a little slimy on me or dry and wrinkly. The solution turned out to be these lid liners - just make sure to store the *unwashed* mushrooms in the jar until you're ready to use them, and use this silicone liner and a metal band to cover them.

My photo doesn't do it justice but, after removing the metal band, you can see the mushrooms have created a natural vacuum on the liner over the course of a couple days' storage; whatever is going on here, the mushrooms create their own ideal environment of just enough moisture to stay fresher for longer. Hope it works for you as well as it has for me, fellow fungi lovers.

Product is as advertised!

Great item and quality! The silicon is thick thus perfect for liquid sealing and less likely to spill. I used this for my jar wherein hot liquid is placed everyday. I did not dare to invert it with its hot contents but I did try it with regular water when I was washing it. It holds and seals well. The high quality silicon works versus other silicones that are too thin. This product is topnotch and is a good alternative to sealing drinks for transport - silicon vs the steel lids.

I gave these as a gift for my milk lady. She has used these on my milk jars and they worked great! They make opening the jar so much easier. And they don't leak. They also make cleaning them and the lids so much easier!

I like these so far. They are easy to clean and work well with the stainless steel bands on here. I hope they last a long time. I no longer have to worry about getting cut cleaning the liners. They form an airtight seal with the stainless steel bands. I recommend them.

These liners fit the jar tops well with the bands screwing on as well as if using the flat metal liners. They're very handy is jarred contents one prefers to not. have contact with metal. Also, have not found leaking to be a problem with these tops.

I love the silicone liners,leak proof, easy to clean and use, just nothing bad to say. I haven’t canned anything with them so I can’t say anything about that but I’ve had no issues with what I’ve done

These are great!

I used these to store my preserved lemons because I dislike when acidic foods corrode the metal rings over time, and they worked like a charm! I'll be ordering some wide mouth ones as well, so I have plenty on hand for vinegar storage too.

Mason jar lids with silicone rings

I’m thinking these will be a lot better. I’d purchased some cheap lids but they didn’t have the rings in them. I think I’m going to be pleased with the sealing part of these. Very colorful too!

Love these lids and liners!

I am slowly replacing all my vast collection of ball jar lids with these stainless steel lids with silicone inserts. They are tremendous!

They seem great! Washed and ready to go. Now I need to select my wide mouth mason jars. Because I live in a studio apartment, must decide which single size set of 6 jars is best to cover all my food storage needs.

Lid liners

I really like this product. I get tight seals when storing food. I use lots of mason jars for food storage and hated not getting air tight seal with the white or black lids. I can now use these.

Stainless Steel Jar Lids with Seals

Bought these once before. They are easy to use, easy to clean, and so far have held up very well. We have one on a doggie treat jar that has been opened several times a day for the last year or so. The seal shows no wear whatsoever. Of course the 304 stainless should last several lifetimes if treated reasonably well. Heirloom lids I would call them.
