HEAT EXCHANGER

TWO-PIECE TUBE PLUGS

Two-Piece Tube Plugs — 5/8 to 1-Inch Outer Diameter


Two-Piece Tube Plugs

How to use the tube plug:

  • Sealing off leaky condenser and heat exchanger tubes without damaging tubesheets.
  • Place correct size ring in tube. (Order by tube Outer Diameter and Gauge)
  • 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.
