What's the deal with pre ordering?
You've got the option to order this item now and be one of the first to receive the new stock as soon as it arrives into our warehouse.
If you’ve bungled the bung on your icebox, then you’ll be able to keep it from leaking and be able to drain it for cleaning again with the replacement Drain Bung from Dometic.
This bung is a genuine Dometic part that will suit your existing CI or WCI Icebox and comes with a gasket included.
I've just measured the plug diameter and it's 19mm so unfortunately, it won't suit a 30mm bung.
