The Dometic GO Jug Replacement Cap is the 63 mm cap-and-gasket set for the Dometic GO / HYD-J11 11L Hydration Water Jug. If the original cap cracked, disappeared during cleanup, or got tightened one too many times, this gets the jug back into service without duct tape or a mystery-bin lid.
Replace the cap, not the whole jug
A good water jug is only useful if it seals. This replacement cap is for the Dometic GO jug’s 63 mm opening and includes the gasket shown in the product photos, so you can fix the failed or missing piece instead of replacing the full jug.
This is a Dometic service part, not an American Adventure Lab-made component. We stock it because small parts like this are exactly what disappear right before a trip, and the right replacement is a lot cleaner than forcing a generic lid to fit.
Bagged Dometic replacement cap set labeled HYD-J11 with SKU 4453001675.
Includes the 63 mm cap and gasket/pour insert shown in the gallery photos.
Refresh the sealing cap on the jug you already own instead of improvising at camp.

Before you order: match your jug to the Dometic GO / HYD-J11 11L jug and the 63 mm cap requirement. If you need a spigot, faucet, vent, or a lid for a different brand of water jug, this is not that part.
Use it like the original part
Install the gasket with the cap, thread the cap on squarely, and tighten it only enough to seal. Over-tightening is a fast way to stress plastic caps, especially when the jug gets bumped around in a vehicle or camp kitchen.

Does it include the gasket?
Yes. The product photos show the cap and gasket/pour insert, and the package label identifies the part as a 63 mm cap and gasket.
Will it fit other water jugs?
Do not assume it will. This page is for the Dometic GO / HYD-J11 11L Hydration Water Jug. It is not listed here as a replacement for RTIC, Reliance, military water cans, or other generic water jugs.
