Tube Plugs

A plug for every type of tube

When you need to plug off leaking tubes in heat exchangers, look no further than Conco. Our crews can accommodate any tube plugging application. Conco offers a full range of plug sizes, styles and materials to match your needs.

Our inventory includes High Confidence Tube Plugs, tested to over 1,000 PSI under a wide range of temperature and vibration conditions. Our line of expanding tube plugs can be used for temporary or permanent plugging. While our EX-3 Expanding Tube Plugs feature an oversized washer to prevent them from being pulled into the tube by the vacuum of the unit, our EX-4 Tube Plugs are designed to be placed inside the tube, recessed just below the tube sheet. Then there are our EX-F Tube Plugs, offering two separate gripping and sealing designs in one plug and sealing to 400 PSI.

Plug in tube

Need a temporary or emergency plug, then check out Conco Fiber Tube Plugs. These plugs install easily, expand when wet and will not damage tube sheets. They can be used in temperatures up to 230° F.

Type-1 Pin, and Type-2 Pin and Collar Tube Plugs come standard in titanium, stainless steel, brass and bronze. They seal at high temperatures, allowing continued use of the unit without major overhaul. They are ideal for use in the tubesheet where tube samples have been extracted.
