Tube Plugs


One Piece Tube Plugs - Condensers - Heat Exchangers - Boilers

Wilson Tube Plugs offer a low cost, quick and efficient method of sealing leaking tubes. They are installed easily so the pressure vessel get back on line. Minimum driving is required to establish a positive seal in seconds.

The tube plug and tube metal should always match. Fiber plugs require minimal driving since they tighten as they come in contact with water, but fiber plugs should not be subjected to temperatures exceeding 105°C (221°F)!

How to use the tube plug:

  • For sealing off leaky condenser and heat exchanger tubes without damaging tube sheets.
  • Place correct size ring in tube. (Order by Tube O.D. and gage)
  • Tapered plug is driven into ring, which is tapered on the inside and is parallel to tube on the outside. This gives even expansion to the ring and a long contact to the seal. Available in a variety of metals: stainless steel 316 or 304, carbon steel and others.
