NPTF (National Pipe Taper Fuel) threads are a type of dryseal pipe thread designed to provide a leak-free seal without the use of sealant. They have a tapered thread profile with a 60-degree thread angle, similar to NPT (National Pipe Taper) threads, but with a modified root and crest design that allows for metal-to-metal contact, ensuring a tighter seal. NPTF threads are commonly used in high-pressure applications in industries such as hydraulics and pneumatics.
