Pipe Thread gages are used to inspect Tapered or Straight Pipe Threads. They are perfect for the inspection of internal fittings. Vermont Gage stocks gages to inspect the following pipe threads, NPT, NPSM, NPTF (Dryseal), and NPSF. Plug gages may be purchased as assemblies or as individual members. Custom pipe threads are quoted upon request.
Thread gauges in this selection are used to identify the nominal size for pipe threads and pipe fittings for plumbing applications. This gauge is specifically designed to ISO Threads, and contains sizes from M5-0.8 to M27-2.0.
Thread gauges in this selection are used to identify the nominal size for pipe threads and pipe fittings for plumbing applications. This gauge is specifically designed to British Standard Pipe Taper Threads, and contains BSPT sizes from 1/8 inch to 3/4 inch.
The Alameda Thread Gage Buyer's Handbook completely describes our thread gages, ring gages, thread setting plugs, thread wires, helical wire coil gages, pipe thread gages, taperlock and reversible style gages, inch and metric gage sizes, gage selection, gage tolerance, and proper gage use.
A Thread Plug GO gage checks the minimum major diameter and the minimum pitch diameter size in a part, the NOGO checks for the hole not to exceed the maximum pitch diameter size in a part. All GSG Thread Plug Gages are manufactured to ASME/ANSI B1.2 or B1.16M. All thread plug gages are made of oil hardened Tool Steel.
Using Thread Gages. Using the principles of GO/NOGO gaging for internal threaded parts, a GO thread plug gage checks the minimum major diameter and minimum pitch diameter, and a NOGO thread plug gage checks that the maximum pitch diameter is not exceeded. The GO gage should thread into the part and the NOGO gage should not.

National Standard Taper Pipe Threads Size NPT Chart - Includes both External and internal Pipe Thread Data. The taper rate for all NPT threads is 1⁄16 (3⁄4 inch per foot) measured by the change of diameter (of the pipe thread) over distance. The angle between the taper and the center axis of the pipe is 1° 47'′ 24"″ (1
See Tap Drill Sizes for NPT Pipe Threads . Note b: Reference dimension. - NPT Thread taper angle = 1/16 taper = 1 deg. 47 min = 0.75 in./ft . - The angle between the sides of the thread is 60 deg. - Thread Designation: The nominal pipe size, number of threads per inch and the thread series symbol in sequence. Ex: 3/8 - 18 NPT
