• FITS WIDE MOUTH LIDS: 10 Reusable Platinum Silicone Seals. Wide Mouth Mason Jars are 3" Internal Diameter. These *WIDE MOUTH* sealing rings are 86mm (3.4") outside diameter, 69mm (2.7") inside diameter, and 3.4mm (.13") thick.
• SUPERIOR QUALITY: Leak Proof, Air Tight, Durable, & Better Design Than Competing Products! Designed for Ball plastic storage caps, Mason Jar Lifestyle stainless steel storage lids, and many other lids. Our rings are thicker and have a groove for a secure fit. The groove goes up, toward the top of the lid.
• THE SAFEST OPTION: BPA and Plastic Free. Made of platinum cured silicone rubber, these seals are dishwasher, freezer, and microwave safe. Silicone is a safe, green, material for food contact, that does not leach chemicals. Platinum cured silicone is more expensive and higher purity than peroxide cured silicone.
• VERSATILE: Perfect for fridge and freezer storage, pantry storage, transporting food or beverage without leaking, home made fermenting lids, and much more! May not provide an air-tight seal when used with wire bail or wire clamp closure jars. Not for canning.

The wide mouth seals are 86mm outside diameter, 69mm inside diameter, and 3.4mm thick. Our silicone sealing lid liners are also available on Amazon, they completely cover the inside of the lid! One piece storage lids are super convenient when you are storing things in the fridge or pantry, but most of them are not air tight and leak proof. These seals will fix that! For best results, use with threaded closure jars. May not provide an air-tight seal when used with wire bail closure jars. These seals will also fit our wide mouth stainless steel storage lids and stainless steel straw hole lids if used with the groove side down. We do have different seals (with a bump instead of a groove) that fit those lids even better, though. Holding the lid under hot running water will help if you are having trouble removing the lid. Lids, jars, and other accessories sold separately.
