HVAC Tube Plugs

Tube Plugs from Thomas C. Wilson offer a low-cost, quick, and efficient method of sealing leaking tubes. Our tube plugs are easily installed, so you can establish a positive seal with minimal driving in seconds and get pressure vessels immediately back online. Wilson Tube Plugs come in a variety of materials and sizes, and we are happy to customize tube plugs according to size and material upon request.

For best results with sealing tubes without damaging tubesheets, please be sure to place the correct size ring in the tube by ordering tube plugs by tube Outer Diameter and Gauge. When ordering tube plugs, please keep in mind that the tube plug and the tube metal should always match. Please contact us if you have any questions about our tube plugs or if you require more information to make a selection.

Vacuum Leak Detector — 1/4" to 3" OD
Vacuum Leak Detector
The Wilson 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.

The Wilson VLD can be used with accessory parts, including the Wilson Tube Plug Snap for 3/8 to 2-inch (9.5 - 50.8mm) Outer Diameter. Additional nozzles are available from 1/4 to 3-inch (6.4 - 76.2mm) Outer Diameter and nozzle extensions are available from 5/8 to 2-inch (15.9 - 50.8mm) Outer Diameter. The Wilson Vacuum Leak Detector is available on a rental basis. Please click here if you are interested in Thomas C. Wilson rental equipment.
