Leak Proof Silicone Sealing Rings Seals for Ball Plastic Caps

• Leak-Proof: Tired of your Mason jar tipping over and leaking into your bag? Our leak-proof silicone sealing rings are the solution. They fit snugly inside one-piece Mason jar lids to keep your food secure and your bag mess-free.
• Premium Quality: These rings are made from platinum-cured silicone, the highest grade available for food contact. Unlike peroxide-cured silicone, platinum curing leaves no chemical residue. They're uncolored, BPA-free, odorless, and completely food-safe.
• Designed for a Perfect Fit: Compatible with many one-piece Mason jar lids, including Ball’s gray leak-proof lids (they may bunch slightly):

  • Wide Mouth: 86mm (3.4") outside diameter, 69mm (2.7") inner diameter, and 3.4mm (.13") thick

  • Regular Mouth: 70mm (2.75") outside diameter, 50mm (2") inner diameter, and 2.6mm (.1") thick
    

There's nothing worse than capping your Mason jar with your leftovers with a regular lid, tossing it into your lunch bag, having it tip over, and leak over all everything! Well lunch time disasters are a thing of the past with our leak proof silicone sealing rings.

Don't want your food to touch the metal or plastic cap at all? Don't worry we've got you covered (pun intended)! Check out our silicone sealing lid liners for regular and wide mouth Mason jars.

Great for:

• Fridge, freezer, and pantry storage

• Fermenting and fridge pickling

• Storing jars on their sides

• DIY airtight lids
  

Tip: Don’t overtighten the lids. If stuck, run under hot water to loosen. Any mild odor disappears after washing.

Get a cleaner, safer, and more reliable seal with our platinum-cured silicone rings.
