Tap In, Pull Out
- Tap the plug in with a small hammer or rubber mallet until it's firmly in place.
- Pull it out with a firm pull from a pair of pliers.
Plugging a leaking tube instead? Puncture it first with the One-Rev Internal Tube Cutter so pressure can't build up behind the plug.

Cork Tube Plug FAQ
What are cork plugs typically used for?
Sealing Fin-Fan®, heat exchanger, boiler, and condenser tubes from outside contaminants during transport, and marking tubes that need attention during work on the unit.
What sizes do you offer?
We stock TP-0000-C through TP-15-C. See the sizing chart, or call us with your tube I.D. and we'll recommend a size.
How quickly can I get them?
We stock more than 500,000 tube plugs across all varieties and sizes. In-stock products typically ship the same day.
Are cork plugs reusable?
It depends on how you use them. For transport or marking tubes during rework, they can be reused as long as you keep them clean and dry. Cork is porous and absorbs any liquid it touches, which can make it unusable for some applications.
How do I install and remove them?
Tap the plug in with a small hammer or rubber mallet until it's firmly in place. Remove it with a firm pull from a pair of pliers.
