2-1/2 in. (63.5 mm) Male NST x 2-1/2 in. (63.5 mm) Male NST Brass Hex Adapter secures to fire hose, hydrants, plumbing, piping, and pumps with one Male NST end and another Male NST end. Machined from durable cast-brass, this adapter allows two female fittings to connect for use with mismatched fire hose couplings, relay supply hose couplings, fire pump suction, fire hydrants, or nozzles.
These adapters include both National Standard 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.
