Goodson Tools and Supplies for Engine Builders of Winona, MN, introduces a Pistol Grip Vacuum Tester. Vacuum Testing is one of the most reliable methods for testing valve-to-seat seal when building a cylinder head. An electric version is already a part of the Goodson product line so when asked why the company was adding another tester, Dave Monyhan, national sales manager, said, “The automotive aftermarket lost a great vacuum tester when the Sioux™ stopped making the 1630 vacuum tester. We’ve been working to add a unit that could take its place.”

The Goodson DVC-2011 Vacuum Tester pulls and holds up to 24 PSI of negative vacuum on 90 PSI of shop air and features quick coupling Robinar fittings. The tester comes with a 4.75” diameter plate and carrying case. Additional plates are available from a 2” diameter to 6” and in two rectangular plates measuring 2”x3” and 3”x4”. James Tapp, Goodson tech services manager, said he’s excited about the new Pistol Grip Vacuum Tester. “It seems like just about everyone has been coming out with one of these over the past couple of years, but we’ve built ours to be more versatile than most. It works pretty much like the old Sioux™ 1630, but we’ve added an optional flexible hose kit so that this one can be used to test smaller, harder to reach areas. We also offer six different vacuum plates for various sized openings.” A variety of replacement and service parts are available. For more information, contact Goodson at 800-533-8010.
