What is NPT? What is NPTF? NPTF vs. NPT
NPT stands for National Pipe Tapered and is a U.S. standard for measuring tapered threads on threaded pipes and fittings. Threaded pipes can give an effective seal for pipes using hydraulic fluids.
NPTF stands for stands for National Pipe Tapered Fuel. NPTF connection is widely used in fluid power systems, even though it is not recommended by the National Fluid Power Association (NFPA) for use in hydraulic applications. The thread is tapered, and the seal takes place by deformation of the threads.
The difference between NPT and NPTF is that NPT requires some type of sealant be placed on the threads before assembling your system, while NPTF creates a strong seal that keeps it from leaking without the need for sealant.
