NPT (National Pipe Taper) and NPTF (National Pipe Taper Fuel) both refer to types of thread used for pipe fittings, but they serve different purposes. NPT threads require a sealant to ensure a leak-proof connection, while NPTF threads are designed to create a dry seal without the need for additional sealants, as they have tighter tolerances and a slightly different thread form to achieve a metal-to-metal seal.
