I want to buy some lily pipes but i want to know what size of tubing the eheim classic 2213 has? 13mm?

The 494 tubing on the 2213 has an ID of 12mm and an OD of 16mm.

You may want to put the inserting end of the tubing in very hot or boiling water to soften it up before inserting the glass pipes.

e??
