The Zago Manufacturing Company introduces its new line of self-sealing fasteners. The new fasteners are designed with a groove under the head to accommodate a rubber O ring which, when compressed, forms a complete seal and permits full metal-to-metal contact.
The self-sealing fasteners provide an airtight, leakproof seal against liquids, air and other gases, and can be removed from equipment and refused without spoiling the sealing action.
