No, NPSM (National Pipe Straight Mechanical) threads are not designed to thread into NPT (National Pipe Tapered) threads. NPT threads are tapered, which allows them to create a seal by wedging, whereas NPSM threads are straight and do not have the same sealing capability. If a seal is required, an adapter or sealant might be necessary to connect these different types of threads properly.
