NPT (National Pipe Taper) and NPTF (National Pipe Taper Fuel) pipe fittings both have tapered threads, but they differ in their sealing characteristics. NPT fittings require a sealing compound or tape to prevent leaks, as the threads alone do not ensure a leak-proof seal. In contrast, NPTF fittings are designed to create a dry mechanical seal without the need for additional sealing materials, as their threads are precision-designed to deform slightly upon assembly, creating a tighter seal.
