Does this adapter go from a bigger hydrant port down to a smaller hose connection, or is it the other way around?

It steps down from a 2-1/2 inch female NST connection on the hydrant side to a 1-1/2 inch male NST on the hose side. So yes, you're reducing from the larger hydrant outlet to fit a smaller hose coupling. That's a common setup in municipal and industrial firefighting rigs where the hydrant port is oversized relative to the attack line being used.

got a hydrant with 2-1/2 female NST threads, will this step me down to 1-1/2 male NST for my smaller hose?
Question by: Freddie P on Mar 3, 2026, 2:15 PM
For stepping between thread sizes, this adapter is set up as 2-1/2 inch female NST on one side and 1-1/2 inch male NST on the other, so it’s meant to connect a 2-1/2 NST hydrant outlet to a 1-1/2 NST connection.
