Test Guns

G150/150A

Find leaking heat exchanger tubes quickly and easily, with the G-150 tube testing gun set. Just connect to plant air, insert the air injection gun in one end of the tube, the plugging gun into the other, and press an air control valve. Air expands the seals on both guns and pressurizes the tube. When the pressure in the tube stabilizes, release the air control valve. Any reduction of pressure will be indicated on the integral pressure gauge to reveal even the smallest tube leak. With the G-150 tube testing gun set, you can pneumatically test from three to ten tubes per minute — all with significantly less operator fatigue and greater operator safety. The set comes complete with three rod and tube assemblies to test tubes from 0.28” to 1.23” (7.1mm to 31.2mm) I.D.

A fast, easy way to individually test and identify leaking heat exchanger tubes to a maximum of 125psi. Requires seals cut to fit the tube ID.G-150 test gun

  • Interchangeable seal and washer sets
  • Light weight: each gun weighs less than 2.1 lbs (1 kg)
  • Uses standard plant air supplies from 40 to 125 psi (2.7 to 8.5 Bar)
  • Standard seal material: Neoprene, Viton®* optional
  • Quality assurance system certified to ISO-9001
  • Quality assurance system that meets requirements of ANSI N45.2, 10CFR50 Appendix B, 10CFR21

G-250

Operating the G-250 Test Gun is simple. Connect shop air to the vacuum gun. Insert the vacuum gun and T-handle into the ends of the subject tube. Press a control valve and an integral vacuum generator quickly and efficiently evacuates the tube. Any loss of vacuum indicated on the gauge indicates a tube leak. The tapered seal design allows you to test a large range of tube ID’s without changing out the seals, washers, or support rods.G-250 test gun

  • Includes two standard seal and washer sets: Allows testing from 0.28″ to 1.45″ (7.1 - 36.8mm). Optional seals available to allow testing to 2.5″
  • Light weight: Gun and T-handle weigh less than 2.1 lbs (1 kg)
  • Uses standard plant air supplies from 40 to 125 psi (2.7 to 8.6 Bar)
  • Standard seal material: Neoprene
  • Quality assurance system certified to ISO-9001
  • Quality assurance system that meets requirements of ANSI N45.2, 10CFR50 Appendix B, 10CFR21

G650/650A

The EST Group G-650 Vacuum Joint Testing Gun distributed by Proplug uses air pressure to generate a vacuum around the tube-to-tubesheet joint to pinpoint leaking connections. Just insert the test gun into the tube end and press the air control valve to  fill the cylinder with air. This expands a seal inside the tube, pulling a second seal firmly against the tubesheet surrounding the tube end. Next press the vacuum control valve to divert air through a venturi, creating a vacuum around the tube joint area. Any  reduction in vacuum shown on the integral gauge indicates a faulty tube joint.

Designed to vacuum test a heat exchanger tube roll joint. Supplied as a kit with manifold for one tube size. Additional manifolds are available. Requires seals cut to fit the tube.G-650 test gun

  • Interchangeable Manifolds: Allows the G-650 to test tube OD’s from 3/8 “ to 1-1/4” (9.52 to 31.75 mm). The G-650A is used for tube OD’s from 1-1/2” to 2-1/2” (38.1 to 63.5 mm)
  • Light Weight: Weighs less than 2.7 lbs (1.2 kg), when equipped with a 3/4” manifold
  • Uses standard plant air supplies from 40 to 125 psi
  • Standard seal material: Neoprene, Viton® optional
  • Quality Assurance System: Meets requirements of ANSI N45.2, 10CFR50 Appendix B, 10CFR21, and is certified to ISO-9001
