Product Overview

Fiber & Wood | Phenolic Tube Plugs

Non-Metal — Emergency & Temporary Applications

USA Industries offers non-metal tube plugs for emergency or temporary plugging of condensers, boilers, and Fin-Fan® heat exchangers. Available in wood, phenolic, or micarta — these plugs install with a tap of a rubber mallet and expand upon contact with water for a simple, effective seal that won't damage your tube sheet.

Materials

Available in wood fiber, phenolic, and micarta — all constructed from non-metal fiber rods that are corrosion resistant and safe for tube sheet surfaces.

How It Seals

Plugs expand upon contact with water — conforming to the tube interior for an effective seal with minimal manpower and time.

Installation

Install with a simple tap of a rubber mallet — safe, easy to use, and easily removed when the job is done.
