Product Overview

Two-Piece Metal Tapered Tube Plugs

Enhanced Sealing for Boilers, Condensers & Fin-Fan® Heat Exchangers

Two-Piece Metal Tapered Tube Plugs offer greater sealing than one-piece plugs while minimizing tube sheet damage. A parallel outer ring with a tapered inner bore delivers even 360° expansion and a longer contact seal — reducing points of failure and protecting expensive tube sheets.

How It Works

A tapered pin drives into a parallel outer ring — the ring expands evenly for a 360° seal along its full length, creating a longer, more reliable contact point than single-piece designs.

Custom Fit

Custom cut to your tube's exact I.D. — provide your tube's inside diameter and we turn down the outer piece for a precise fit. Custom sizing prevents leaks and eliminates guesswork.

Materials

Available in over 20 metals including brass, carbon steel, 304/316/416 stainless steel, and aluminum. Custom coatings available upon request — match plug material to tube material for optimal performance.

Availability

500,000+ tube plugs in stock and ready to ship — in-stock items ship within 24 hours. Production capacity exceeds 5,000 plugs per day.

Installation — Easy & Quick

Place the ring inside the boiler, condenser, or heat exchanger tube.

Drive the tapered pin into the ring — causing it to expand outward for a full 360° seal.

The ring seals along its entire length — minimizing points of failure and tube sheet damage.

Important Note

You must provide the exact I.D. of your tube so we can turn down the outer piece for an exact fit. It is best practice to use plug and pin materials that match or are compatible with the tube being plugged.
