Tube Plugs - One-Piece — 3/8" to 3" Outer Diameter
One-Piece Tube Plugs are available in sizes ranging from 3/8 to 3-inch (9.5 - 76.2mm) Outer Diameter and are well-suited for use in condensers, heat exchangers and boilers. They come in a variety of materials, including brass, carbon steel, stainless steel, fiber and monel (made to order). One-Piece Tube Plugs are packaged 10 per box, except 1-1/2-inch Outer Diameter or larger tube plugs which are packaged individually. Please note that fiber tube plugs require minimal driving since they tighten as soon as they come into contact with water. It is also important to remember that fiber tube plugs should never be subjected to temperatures exceeding 221°F (105°C).
The Vacuum Leak Detector (VLD) is a simple test instrument used by manufacturers and users of condensers, heat exchangers and other tubular apparatus to identify leaky tubes from 1/4 to 3-inch (6.4 - 76.2mm) Outer Diameter. With the VLD, one user can seal the far end of a tube with a snap type tube plug by pressing the rubber-coated nozzle into the near end of the tube and depressing the trigger. A steady Gauge reading indicates a good tube, while a falling vacuum indicates a leaky tube. Using a 90 psi dry clean air, a typical tube (1-inch Outer Diameter x 20-Gauge and 20-feet in length) can be tested in 6 to 8 seconds. The VLD weighs 2-1/4 pounds and is equipped with a muffler, providing quiet operation even in confined areas.
Two-Piece Tube Plugs are available in sizes ranging from 5/8 to 3/4-inch (15.9 - 19.1mm) Outer Diameter and come in stainless steel 316 or 314, carbon steel as well as other materials. Two-piece tube plugs are designed for use in condensers and heat exchangers.
