Legend Valve 322-614 A93 coupling

This Legend Valve 322-614 A93 fitting connects a 1-1/2 inch NPSH hose thread to a 1-1/2 inch NPT pipe thread. It is a plumbing component designed to join fire hose assemblies to rigid piping systems. The part is supplied new from the manufacturer.

Fire hose to pipe thread adapter

Installers adapting fire hose connections to standard NPT piping will use this coupling. It does not suit applications requiring matching thread types on both ends or connections for smaller diameter lines. Buyers needing different thread standards or sizes should select another fitting.

NPSH to NPT thread configuration

The defining specification is the mixed thread interface: one side cut to 1-1/2 inch NPSH and the other to 1-1/2 inch NPT. This mismatch determines whether the coupling matches the two components being joined. Verify both thread requirements before ordering.
