Airtight 70mm 86mm Mason Jar Lids Food Grade Stainless Steel Canning Mason Jar Lids

Ensure absolute freshness and long-term preservation with our Airtight Food Grade Stainless Steel Mason Jar Lids. Engineered to create a perfect, leak-proof seal on both 70mm (regular mouth) and 86mm (wide mouth) jars, these lids are the ultimate solution for safeguarding the flavor, nutrients, and quality of your contents. Constructed from premium 100% stainless steel, they are inherently rust-proof and will never corrode or transfer metallic tastes, unlike common zinc-plated alternatives, guaranteeing the purity of your food products.

The lid features an integrated, high-quality silicone sealing ring that flexes to form an impenetrable barrier against moisture, oxygen, and contaminants. This robust construction makes them ideal for everything from dry goods storage and vacuum sealing to commercial canning and refrigerated goods. Durable, dishwasher-safe, and designed for countless reuse cycles, these lids offer a sustainable, high-performance closure system that protects your products and elevates your brand’s commitment to quality.
