Our clear glass general purpose jars are as functional as they are economical and feature a 70 mm lug finish. A lug finish consists of several tapered ridges designed to mate and require only a partial turn to seal the cap.
Gold Metal Lug Cap Included
These lug 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.
