38 mm Black Metal Lug Caps with Plastisol Liner
These caps have an acid-resistant liner that is ideal for tomato-based recipes and other acidic foods. The liner draws a vacuum on any lug-finish jar. This cap is designed for hot fill steam application in which steam heats the jar and creates the vacuum. Recommended product fill temperature for this cap is >185 degrees F. Cap is NOT recommended for water bath filling. Lug caps must be paired with a container that feature a lug finish. A lug finish consists of several tapered ridges designed to mate and require only a partial turn to seal the cap. Lug caps are not compatible with containers that feature a continuous thread (CT) finish.
