Pop-A-Plug® G-650 Vacuum Joint Testing Tool

Quickly test expanded tube-to-tubesheet joints for leakage. Ideal for heat exchanger manufacturers or companies performing retubing operations. The G-650 Vacuum Joint Tester seals the tube I.D. and the tubesheet face, then evacuates the tube end at the joint. A loss of vacuum indicates a leaky tube joint. Interchangeable manifolds and seal & washer sets allow the G-650 Tool to test tube-totubesheet joints on 3/8” to 1¼” (9.5mm to 31.8mm) O.D. tubes. Larger G-650A Vacuum Joint Tester will accommodate tube O.D. sizes from 1½” to 2½” (38.1-63.5mm). Digital Pressure Gauges are also available. Uses standard compressed air supply – 40 to 125 PsiG (2.7 to 8.5 BarG).
