Just a thought on replacements large diy outlets will have some kitchen, bathroom sized plastic pipe if needed. A tropical fish/aquarium supplier may have some differing sizes, as well? I quick search on ebay/Amazon should find something as well.
Also in your local supermarket you could look for aluminium foil and grease proof paper inner rolls if the size matches.
The actual port length should be no longer than the depth of the cabinet, minus the port diameter as a rule of thumb, but in fact could be much less.
