NPSM (National Pipe Straight Mechanical) threads are straight threads that are compatible with NPT (National Pipe Tapered) threads when used with a sealing component like an O-ring or gasket. NPSM threads are typically used in mechanical joints where a seal is achieved through a separate sealing method, not by the threads themselves. Therefore, while NPSM and NPT threads can be used together, the connection requires an additional sealing element to ensure leak-proof performance.
