An NPSM swivel is a type of fitting that uses National Pipe Straight Mechanical (NPSM) threads combined with a swivel nut, allowing for easy connection and disconnection without twisting the attached hose or pipe. The NPSM threads are straight (not tapered) and typically require a sealing washer to prevent leaks. This design is commonly used in hydraulic and plumbing applications.
