National Standard Taper Pipe Threads Size NPT Chart
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"″ (1.7899°).
Straight Pipe Threads Table Chart ANSI – WESTport Corp.
Unauthorized use is prohibited. The following table chart defines Straight Pipe Threads for Mechanical Joints, NPSM and NPSL ANSI/ASME B1.20.1, American Pipe Threads Standard. Straight pipe threads are designated NPSC = National Pipe Straight Coupling. Also generically referred to as "IPS Threads" or "Iron Straight Threads".
How to Measure a Taper Pipe Thread & Choose the Right Gauge
The L1 gage is the primary gage for NPT threads, as it determines the basic acceptability of the thread. NPT L2 or L3 Thread Plug or Ring Gauge: This gage checks the thread form and the pitch diameter at the wrench-tight engagement position, which is the point where the threads of the male and female parts are fully engaged and sealed. The L2 ...
Which NPT Taper Pipe Ring Gage should I use? - WESTport Corp.
1. NPT L1 Ring Gauge: The NPT L1 ring gauge is designed to measure the external threads of a pipe using the National Pipe Taper (NPT) standard. It has a cylindrical shape with a threaded outer surface that matches the corresponding NPT pipe thread. The L1 designation indicates that it is a ring gauge used for checking the tightness and accuracy ...

Overview of Taper Pipe NPTF 6 Step Plug Gages - WESTport Corp.
Taper pipe NPTF 6 step plug gage is required by the NPTF class 2 threads. It is also known by another name which is Crest-and-Root Truncation Gage. Taper pipe NPTF 6 step plug gage is not threaded, rather, it has six steps grounded into it. The tool is used by inserting it into the hole and then reading the pairs which tell us the high and low ...
What You Should Know About the ANPT 6-Step Plug Gage
ANPT or “Aeronautical National Pipe Taper” Plug Gages are devised for their use on aeronautical components such as plugs, pipes, and other similar fittings that need a thread joint that is sealed mechanically. For these applications, gaskets, O-rings, or straight threads are not applicable. ANPT 6-Step Plug Gage is also used in the same ...

Additionally, the NPTF 6 step plug inspects the crest truncation or profile of the internal threads and is used in conjunction with L1 plug. All NPT pipe thread plug and ring gages are manufactured per ANSI/ASME B1.20.1, and all NPTF pipe thread plug gages are manufactured per ANSI/ASME B1.20.5. Taperlock Thread Gage:
Overview of Taper Pipe NPT L1 Plug Gages – WESTport Corp.
Taper pipe NPT L1 Plug Gage is used by quality inspectors, manufacturing engineers, technicians, and machinists for the inspection of thread components and their precise calibration. They are an essential part of any quality control process to ensure the threaded components are made with the required calibration and are free of any obstruction.
