The sealant is a soft pliable olefin based material designed to flow between the bearing shoulder and threads of the fastener, and the abutting bearing surface of a receptacle as the fastener is tightened into the receptacle thereby creating a tight seal. The fastener with an integral sealing element is reusable and does not require additional curing or heating after installation.</p> |
