It installs inside the female coupler and seals against the male adapter to prevent fluid leaks during the transfer of petroleum, chemicals, or other liquids. This gasket should be replaced when it becomes cracked, swollen, or hardened in order to maintain a reliable, leak‑free connection. Although the inventory lists this as a "dust cap gasket," it is actually a standard secondary‑seal gasket for active coupling use.
