New Vista will be showcasing some of our most popular powered thread gaging units including the Handheld RT & CRD Unit, the SCD Machine, and the STH Unit. Attendees will be able to use these units themselves to get a feel for just how easy they are to operate. If you would like to see these units in operation beforehand, check out our YouTube page.

New Vista will be located in Booth #3326,

Powered Thread Gaging: At Your Fingertips

The New Vista Handheld RT Thread Unit being held by our very own Jim Audette.

The trend to replace hand gaging with powered thread verification is a prime example of technology making manufacturing safer & more efficient. Gaging threaded features has traditionally been done by hand, however, this is often tedious and allows room for operator error or injury. That’s where the New Vista Handheld RT Thread Unit comes in. The RT Thread Unit allows an operator to quickly power a thread gage into (or onto) and back out of (or off of) a thread to ensure assemblability. Not only will you find that your inspection time is greatly reduced, but the risk of repetitive motion injuries is all but eliminated when using the RT. The RT Thread Unit Kit contains everything that you will need to start verifying your threads with your standard taper shank gages.

The RT Thread Unit Kit includes:

  • One RT Thread Unit equipped with a Type FP Chuck
  • Three tool adapters for taper shank gages (handle size 0, 1, and 2)
  • One torque adjustment tool
  • Two 14.4v rechargeable lithium-ion batteries
  • One battery charger

Hand Gaging of NPT (American Pipe) Threads

Illustration to show what gages are necessary to verify NPT threads.

            There are two kinds of American pipe thread, NPT and NPTF.  Both of these are tapered threads, but when screwed together tightly, the NPT, and NPTF Class 1, leaves voids at the root and crest of the threads, which, to prevent spiral leakage, need to be filled with a sealing compound at assembly.  The NPTF Class 2 (Dryseal) presumably leaves no voids, and consequently requires no sealer. NPTF threads come in two classes: Class 1 & Class 2.
