Dometic 4453001676 is the OEM HYD-J11 63mm spigot cap and gasket for Dometic HYD Series water-system applications. It replaces a missing, cracked, or leaking cap so the spigot opening stays sealed when the system is not in use.

When this HYD-J11 cap and gasket is the right repair

Use this part when your original 63mm spigot cap is damaged, no longer sealing, or missing from the HYD Series assembly. The cap and gasket help protect the opening from debris and help prevent leaks or water loss at the spigot connection.
