• Parallel or straight pipe thread. • Tapered pipe thread. Take a look at a selection of ISM's metal threaded fittings and plastic threaded fittings. These provide examples of the most common pipe thread types in use. Tapered pipe threads. Piping and fittings are primarily used to carry liquids and gases Generally, available threaded fittings adhere to common standards; British Standard Pipe (BSP) and the National Pipe Thread (NPT) are two of the most common. It can be National Pipe Thread is an American standard defined in ASME B The most popular series is Tapered Pipe Thread (NPT). However, other series, such as NPTSC and Here’s a breakdown of the differences between them: NPT (National Pipe Thread) NPT refers to a type of tapered thread used in the United States for pipes and fittings. It has a taper of , which means the diameter of the thread decreases as you move towards the end of the pipe NPT means National Pipe Taper. NPS stands for National Pipe Straight. It's not tapered and is used mostly in electrical fittings We look at some key differences between the two thread styles. What is NPT? NPT, short for National Pipe Thread, is the US standard for tapered threads on pipes and fittings. These are the most common types of seals used in pressure calibration systems and are quite different from the thread on a regular bolt and nut because NPT (National Pipe Taper) is a general-purpose tapered pipe thread, and NPTF (National Pipe Taper Fuel) is a dryseal tapered pipe thread. Visually, NPT and NPTF pipe threads look identical. Both thread types rely on thread interference for tight, robust connections. This thread interference is made possible primarily by their 9 Oct 03 I have a drawing which displays FNPT. I am familiar with NPT and its variants but not this one. What about FPT. Any info is appreciated. FredGarvin (Mechanical) 9 Oct 03 Most likely a shorthand for female NPT. Do they give the full thread callout? Nellysdad (Aerospace) (OP) 9 Oct 03

Type. – NPT stands for National Pipe Thread or sometimes called National Pipe Taper Thread. NPT is the American standard tapered thread also known as The two main types of pipe thread styles are National Pipe Thread (NPT) and British Standard Pipe (BSP). So, what is the difference between NPT and BSP? Things You Should Know. NPT threads are the national US standard for pipe fittings. MIP fittings are a type of NPT thread. NPT threads are usually used for low-pressure, residential pipes while MIP fittings are used for high-pressure, industrial pipes. NPT threads are tapered and slightly thinner at the bottom NPT fittings are sub-divided into female fittings: FPT, FNPT, NPT(F) and male fittings: MPT, MNPT, NPT(M) Some sources refer to NPT as IPT (Iron Pipe Thread). IPT (Iron Pipe Thread) is equivalent to NPT; Some sources also refer to IPS (Iron Pipe Straight); using IPS risk confusion with NPS listed below If you’re wondering about the difference of MNPT vs NPT, MNPT is the specific NPT male thread. While in the case of NPT vs NPTF, NPTF is the specific female NPT fitting thread
