Puncture, Tap, Seal
- Puncture the tube so pressure can't build up behind the plug. The One-Rev Internal Tube Cutter does it in a single revolution.
- Tap the plug in with a rubber mallet.
- Let water do the rest. The fiber expands on contact with water and seals against the tube.

Non-Metal Plug FAQ
What are non-metal tube plugs used for?
Emergency or temporary plugging of condensers, boilers, and Fin-Fan® heat exchangers.
How do fiber plugs seal?
The fiber expands on contact with water and conforms to the tube interior for an effective seal.
What's the maximum temperature?
Never subject wood, micarta, or phenolic fiber plugs to temperatures above 230°F (110°C).
Will they damage my tube sheet?
No. The non-metal fiber is corrosion resistant and safe for tube sheet surfaces.
