NPSM (National Pipe Straight Mechanical) and NPTF (National Pipe Taper Fuel) are both types of threads used in piping systems, but they differ in design and application. NPSM threads are straight and primarily used in mechanical joints, relying on a gasket or o-ring to seal, whereas NPTF threads are tapered and designed to create a seal without additional sealing materials, as the threads themselves provide a dry-seal. These differences make NPTF suitable for high-pressure systems where a leak-proof seal is critical, while NPSM is more commonly used in low-pressure applications.
