53 mm Black Metal Lug Caps
Our metal lug caps have an acid-resistant plastisol liner that is ideal for tomato-based recipes and other acidic foods. 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.
