How do you determine NPT fitting size?
As a general “rule of thumb” an NPT thread is approximately 1/4″ (0.25”) larger than its “name.” For a 1/4″ NPT fitting the “nominal” OD is 0.533”. NPT fittings are slightly tapered so the “nominal” diameter is the diameter in the middle of the threaded portion, as measured by the top (crest) of the threads.
What is the diameter of 1/2 NPT?

Should you use Teflon tape on NPT fittings?
NPT threads are designed to be used with a sealing compound such as Teflon tape to create a leak-free seal, whereas NPTF threads form a mechanical seal by crushing the entire thread form. If NPT is used without a sealing compound then there can be leakages or other unpleasant issues.
Can you over tighten NPT fittings?
Over-tightening the connection can easily split the female portion of a pipe thread connection; this is especially an issue when installing male pipe thread fittings into cast iron ports on valves, motors, and cylinders. Using a liquid thread sealant for NPT connections is recommended over using Teflon tape.

What is difference between NPT and BSP thread?
Both NPT and BSP are pipe thread standards for screw threads used on pipes and pipe fittings to seal pipes. With NPT, the peaks and valleys of the threads are flat. In BSP, they are rounded. Secondly, the NPT angle of the thread is 60 degrees and the BSP angle is 55 degrees.
Is pipe thread the same as hose thread?
Hose threads are almost always the same size, ¾”. Whereas pipe threads can vary greatly from one manufacturer to another and one system to another as well. Hose threads and pipe threads are not compatible with each other and cannot be interchanged with systems using one or the other.
How far does a pipe thread into a fitting?
If you are using 1/2-inch pipe, add 7/16 inch per end; and add 1/2 inch per end for 3/4-inch pipe. Therefore if you plan to use 3/4-inch pipe to join two fittings 36 inches apart, you would need a pipe 37 inches long (adding 1/2 inch on either end to allow for penetration into the fittings).
What type of thread is washing machine hose?
