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.

Fitment and part-number checks

  • OEM Dometic service part number: 4453001676
  • HYD-J11 label description: 63mm spigot cap and gasket
  • Designed for Dometic HYD Series spigot/fill applications that use this cap style
  • Compare your original cap diameter, gasket shape, spigot opening, and part number before ordering
  • Not a universal cap; similar-looking caps can differ by diameter, thread/seat shape, and gasket fit

What is included

The photos show the packaged Dometic HYD-J11 service part and the loose cap/gasket views so you can compare both the outside face and inside sealing shape. Use the package label and part number to confirm this is the replacement you need.

Helpful buying note

If your old cap does not show part number 4453001676 or your spigot opening does not match the 63mm HYD-J11 style, use ERVP's AI Live Chat with photos of your original cap and water-system label before ordering.
