Canning Jar Lid - Small Mouth 1 pc Metal

This 70-450 (70G) Metal lid cap has a continuous thread with a Plastisol Liner. This lid has ridges along the  outer sides and smooth top with a stacking feature along the rim. Plastisol lined caps are known to be a perfect option for hot-fill processes such as canning. After the non-removable plastisol liner is heated/warmed from the product temperature, it will solidify and create an airtight, hermetic seal.
