The thread profile of National Pipe Taper Fuel (NPTF) threads is similar to that of National Pipe Taper (NPT) threads but with a key difference: NPTF threads are designed to create a dry seal without the need for sealant. This is achieved by having slightly different thread dimensions and a more precise thread profile, allowing for a metal-to-metal seal that ensures a leak-proof connection.
