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°).

How to Measure a Taper Pipe Thread & Choose the Right Gauge
Q: How often should taper thread gauges be calibrated? A: Calibration frequency depends on usage intensity but adhering to manufacturer guidelines and industry standards is recommended. Q: Can the same gauge be used for different sizes of NPT threads? A: No, each NPT thread size requires a specific gauge tailored to its dimensions and taper ratio.
Which NPT Taper Pipe Ring Gage should I use? - WESTport Corp.
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.
Which NPT Taper Pipe Plug Gage should I use? - WESTport Corp.
The NPT L1 plug gauge is designed to measure the internal threads of a pipe using the National Pipe Taper (NPT) standard. It has a tapered end with a specific angle and pitch that matches the corresponding NPT pipe thread.
Thread Mills, Helical Metric/NPT and NPTF - WESTport Corp.
Thread mills generally are used for creating threads in large diameter holes where is not feasible to use taps. Helical flute design reduces thread chatter and improves product thread finish and quality. Standard inch and metric sizes are available in …
Straight Pipe Threads Table Chart ANSI - WESTport Corp.
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
Thread Plug Gages - Every Thread Plug Gauge Imaginable
The NPT L1 and the NPTF L1 plugs inspect the functional size or hand tight engagement of couplings or an internal thread. Or the NPTF L3 plug inspects the wrench engagement and taper of couplings or internal threads and is used in conjunction with the L1 plug.
Female and Male Thread Gages: Explaining Sizes and Differences
The Pitch Diameter Thread gages are measured by diameter, and by pitch diameter. The diameter is the distance across the opening of a female gage, or across the head of a male gage. The pitch diameter, however, is the distance between the threads as it spirals up/down in the center of the gage or around the head of the gage. The pitch diameter often indicates how …
Fittings - Unified Alloys
Threaded and socket weld fittings are used for small diameter pipe sizes 2" NPS and down. The majority of the screwed fittings will have female (internal) threads per NPT (National Pipe Thread).
