Legend Valve 450-797P 2" x 1-1/2" Press x MNPT Reducer Adapter

2" x 1-1/2" Press x MNPT Reducer Adapter

This Legend Valve fitting joins a two-inch press connection to a one-and-a-half-inch male NPT thread. It suits plumbers and facility technicians who need to transition between press-fit copper or stainless systems and threaded pipework. The adapter is new and ships directly from the manufacturer. California Proposition 65 warnings apply for cancer and reproductive-harm chemicals.

Sustained leak resistance under pressure

The press end creates a permanent mechanical seal that resists vibration and thermal cycling better than a threaded joint alone. Once pressed, the connection does not rely on thread compound or tape to maintain integrity over long service periods. The reducer geometry maintains flow while stepping down the line size. No performance degradation is expected when the fitting is installed to the manufacturer's pressing procedure.

Replaces separate reducer and adapter assemblies

Installers can remove a two-piece reducer-plus-adapter combination and fit this single body instead, cutting potential leak paths and reducing installation time. The jump is worth it on new press-system builds or when retrofitting threaded branches onto existing press mains where space and joint count matter. Threaded-only systems gain no advantage from the press end.
