Types of pipe threads
What are the 3 basic thread types?
There are three standard thread series in the Unified screw thread system that are highly important for fasteners: UNC (coarse), UNF (fine), and 8-UN (8 thread).
What is NPT vs MIP?
As previously mentioned, NPT indicates the defined standard from ANSI – but many people use MPT/MIP and FPT/FIP interchangeably. MPT stands for Male Pipe Thread and MIP stands for Male Iron Pipe which both indicate a male fitting with NPT threads.
What type of thread is used on a pipe fitting?
National Pipe Threads (NPT) have tapered threads. These are the most common threads used for general purposes. NPT threads are designed with a 60 degree thread angle, and are used for joining and sealing pipe to fittings in low pressure air or liquids and also mechanical applications.
Is NPT and UNF the same?
UNF is Unified Fine thread, the successor to the obsolete National Fine (NF) thread. NPT National pipe thread is used (in the U.S.) for plumbing of water and gas pipes, and threaded electrical conduit. NPT is defined by ANSI/ASME standard B1. 20.1, American National Standard Taper Pipe Thread.
What does FIP pipe stand for?
Female Iron Pipe
F.I.P.: Female Iron Pipe. Describes an internal pipe thread end connection, verses external.
What is FIP thread?
Simply, FIP is pipe that is threaded on the inside. As a female, it accepts the male pipe, which is threaded on the outside. The male end is twisted inside the female until it is snug. In order to keep a proper seal, Teflon tape is needed around the male threads.
What is BSP and UNF?
BSF and BSW are British measurement systems, while UNF and UNC are American measurement systems. BSF and UNF are the fine thread systems, while BSW and UNC are the coarse thread systems. The difference between BSF/BSW and UNF/UNC is dual: The thread angle.
How do you know if a thread is BSP or NPT?
How do I identify a thread?
Is NPT and MPT the same?
​NPT. NPT stands for National Pipe Thread and is an American standard thread. It may also be reffered to as MPT , MNPT or NPT (M) for male external threads and FPT, FNPT or NPT(F) for female interal threads.
What does MIP fitting mean?
An MIP fitting is one of two components in heavy-duty, threaded-piping connections. MIP typically stands for Male Iron Pipe (it might also refer to other building materials such as copper or steel). The other component is the FIP, which stands for Female Iron Pipe.
Is NPT compatible with FIP?
FIP Female Iron Pipe (interchangeable with NPT) FIP, Female Iron Pipe, or Female International Pipe- Similar to FPT, FIP connect NPT pipe together with internal threads.
What does NPT mean in fittings?
National Pipe Taper
NPT stands for National Pipe Taper — pipe and fittings have a tapered thread profile. The tapered thread seals use an interference fit between the male and female threads. NPT fittings should never bottom out in assembly. By hand assembly only, the pipe or fitting should only screw in part way before jamming.
What is FIP vs MIP?
MIP and FIP
MIP (male iron pipe) and FIP (female iron pipe) are both pipe fittings with NPT threads. MIP refers to fittings with male threads, and FIP refers to fittings with female threads. Despite their names, MIP and FIP are not always made of iron; they are commonly made from steel and brass as well.

What is the difference between MIP and MPT?
MIP is Male Iron Pipe. As the Pure Water Gazette points out, sometimes FIP is called FPT or Female Pipe Thread. And MIP is called MPT or Male Pipe Thread. To make matters worse, sometimes they are referred to as NPT or National Pipe Thread.
What does CTS stand for in plumbing?
CTS: copper tubing size. NPS: nominal pipe size. OD: outside diameter. ID: inside diameter.
What is the difference between FPT and NPT?
National Pipe Threads (NPT) have tapered threads.
