Key item features

  • 【3.7” Diameter for Standard-Mouth Jars】These rubber jar seals have a 3.7-inch diameter, specifically designed to fit standard-sized mouth glass jars—one of the most common jar sizes used for canning, storing dry goods, or preserving homemade jams, pickles, and sauces. The precise diameter ensures a perfect fit, so the seal sits securely on the jar’s rim without being too loose (which would cause leaks) or too tight (which would make it hard to attach or remove). Whether you’re replacing old, worn-out seals on your existing canning jars or stocking up on spares, these seals are compatible with most standard-mouth glass jars, making them a versatile addition to your kitchen supplies.​
  • 【Food-Grade Rubber for Safety】Made from high-quality food-grade rubber, these seals are safe for direct contact with food—eliminating concerns about harmful chemicals, odors, or toxins leaching into your stored ingredients. Food-grade rubber is tested to meet strict safety standards, ensuring it is non-toxic, odorless, and free from substances that could contaminate food. This is especially important for long-term storage (like canned goods or dried herbs) where the seal is in constant contact with food. The rubber also doesn’t absorb flavors or odors, so it won’t transfer any unwanted tastes to your jams, pickles, or dry goods.​
  • 【Leakproof & Moisture-Resistant Sealing】The primary function of these rubber seals is to create a leakproof, moisture-resistant barrier between the jar’s lid and rim. When paired with a jar lid, the rubber seal compresses to fill any small gaps, preventing air, moisture, dust, or insects from entering the jar. This keeps the contents inside fresh for longer—whether you’re storing dry goods like beans, rice, or flour (which can absorb moisture and go stale) or preserved foods like jams (which can spoil if exposed to air). The seal also prevents liquid leaks, so you can safely store liquid-based ingredients (like oil or vinegar) without worrying about spills when moving the jar.​
  • 【Durable & Reusable】These rubber seals are built to last, with high-quality rubber that maintains its elasticity and shape over time. Unlike cheap, thin rubber seals that crack, harden, or lose their seal after a few uses, these seals are thick and resilient, able to withstand repeated use and cleaning. They can be reused multiple times (as long as they remain intact and free from damage) for canning seasons or regular storage, making them a cost-effective choice compared to disposable seals. The rubber is also resistant to aging, even when exposed to temperature changes (like in refrigerators or pantries), so it retains its sealing performance for years.​
  • 【Versatile for Multiple Storage Needs】Beyond canning, these rubber seals are useful for a wide range of kitchen storage tasks. They can be used with standard-mouth glass jars to store homemade snacks (like granola or trail mix), baking ingredients (like chocolate chips or nuts), or even non-food items (like small craft supplies or office pins). They are also ideal for preserving seasonal foods—like summer berries turned into jam or fall vegetables turned into pickles—ensuring that you can enjoy homemade treats year-round. Whether you’re a home canner, a busy parent, or someone who loves organized kitchens, these rubber seals simplify storage and keep your ingredients fresh.​
