The National Pipe Taper Fuel (NPTF) thread specification is a dry-seal pipe thread designed to provide a leak-proof seal without the need for sealants, as opposed to the standard NPT (National Pipe Taper) threads. The NPTF thread has slightly different tolerances, with a more controlled thread crest and root, allowing for a metal-to-metal seal when properly tightened. This makes NPTF suitable for applications where the avoidance of leakage is critical, such as in fuel and hydraulic systems.
