Brass Hex Adapter | 1-1/2 in. | F NPT x F NST

1 1/2 in. (38.1 mm) Female NPT x 1 1/2 in. (38.1 mm) Female NST Brass Hex Adapter secures to fire hose, hydrants, plumbing, piping, and pumps with one Female NPT end and another Female NST end. Machined from durable polished-brass, this adapter allows two male fittings to connect for use with mismatched fire hose couplings, valves, supply hose, attack hose, or nozzles.

These adapters include both National Pipe Thread and National Standard Thread, and are especially useful when conducting mutual-aid operations in another city or county with different thread standards, and can be tightened or loosened easily using the hex-shaped wrench boss.
