Split Two Pieces Mason Jar Canning Lids and Bands Leakproof Metal Caps and Rings

Engineered for superior preservation performance, our two-piece mason jar lid system features precision-formed metal caps and matching bands that create a perfect airtight seal. The separate design allows the flat lid to form a secure bond with the jar rim while the band provides consistent pressure during processing and storage. Made from food-grade tinplate with advanced sealing compound, these lids ensure reliable performance through commercial canning cycles and long-term storage.

The rust-resistant bands feature easy-grip ridges for secure handling, while the lacquered lids resist corrosion and acidic contents. This professional-grade lid system maintains seal integrity through thermal processing and repeated use, meeting the demands of high-volume food preservation operations.
