Heat Exchanger Tube Plugs

Products

Heat Exchanger Tube Plugs

are precision-engineered solutions used to seal leaking, damaged, or retired tubes in heat exchangers, condensers, boilers, and coolers. These plugs help restore system integrity, prevent cross-contamination, and allow continued operation without full equipment replacement.

Our tube plugs are manufactured to fit a wide range of tube sizes and materials, available in tapered, expandable, mechanical, and welded plug designs. Metalok plugs are crafted from SS 304/316, Monel, Inconel, Brass, Copper, Duplex, Titanium, and other corrosion-resistant alloys to suit various pressure, temperature, and media conditions.

Precise Fitment
Available in metric and inch sizes to suit tubes from 1/4” to 2½” OD or as specified.
Material Versatility
Manufactured from materials compatible with tube and tube sheet to prevent galvanic corrosion.
Expandable or Mechanical Locking Design
Provides a secure, leak-tight seal with easy installation.
Tapered & Straight Plug Options
Ideal for temporary or permanent sealing applications.
Pressure-Rated Construction
Designed to withstand system pressures up to 10,000 PSI, depending on type.

Seals Leaking Tubes Quickly
Stops fluid crossover or pressure loss without costly shutdowns.
Extends Heat Exchanger Life
Allows partial tube decommissioning instead of full unit replacement.
Reduces Maintenance Downtime
Plugs can be installed during scheduled or emergency outages.
Protects System Efficiency
Prevents contamination or mixing of fluids within the exchanger.
Minimizes Risk of Damage
Avoids damage to nearby tubes by using non-invasive sealing techniques.
