Description

This is a 33-400 black, ribbed, continuous thread cap with a foam liner. The foam liner creates an air-tight seal as long as the cap is screwed on tightly to the container. Foam liners are many-use liners and remain snugly tucked inside the cap. This lid is made of polypropylene which is a great plastic because of its durability.
