The male side of this adapter will only thread into a 1 1/2 inch NH or NST nozzle or female fitting .
National Hose (NH) is the same as National Standard Thread (NST) aka "Fire Hose Thread" is the most common thread type in use by United States fire departments today.
When NH or NST threads are connected, they use a gasket to create a seal to prevent water leaking. Spanner wrenches are used to tighten and untighten two adapters.
