What's the proper name for a wire waterproof

[03mustangdude]

Need to drill a 1/2 hole in some plastic for a project and need to run some wire, need to waterproof it and have it a little heat resistant, bought them before in-store but couldn't find any yesterday. What is the name of those things so I can buy them online

You talking about heat shrink tubing?
