A 1/4 NPTF (National Pipe Taper Fuel) thread is a type of dryseal pipe thread commonly used in fluid power and fuel applications to create a leak-proof seal without the need for sealants. The nominal size 1/4 refers to the approximate inside diameter of the pipe that can be connected with this thread. The 1/4 NPTF has an outside diameter of approximately 0.54 inches (13.72 mm) and a thread pitch of 18 threads per inch.
