Reducing Coupling 1-1/2" x 3/4

This reducing coupling joins a 1-1/2 inch fitting to a 3/4 inch press connection in plumbing systems. It is manufactured by Legend Valve for use in water supply or hydronic piping where a size transition is required. The component is supplied new and ready for installation.

Fitting x Press Configuration

The fitting-by-press design allows one end to connect to a traditional fitting while the other accepts a press-tool joint. This arrangement reduces the number of separate adapters needed when changing pipe diameters. No additional software or accessories are included with the coupling.

Verify Pipe Sizes and Press Tool Compatibility

Confirm that the existing pipework matches the 1-1/2 inch and 3/4 inch dimensions before ordering. Ensure the press tool and jaw set on site are rated for the coupling's press end. The product carries a California Proposition 65 warning for chemicals known to cause cancer and reproductive harm.

Questions about this item

Will the press connection on the 450-430P coupling need re-pressing or seal replacement over time?

The press connection creates a permanent mechanical joint; no routine re-pressing or seal replacement is required once installed correctly.

What pressure or temperature limit will the 450-430P reducing coupling reach first during continuous hot-water circulation?

The coupling is rated for standard plumbing pressures and temperatures; the system’s pressure relief valve or boiler high-limit control will activate before the coupling reaches its design limit.

Does the 450-430P coupling generate noise or heat when water runs through it all day?

The fitting has no moving parts and adds negligible flow restriction, so it produces no audible noise and no measurable heat rise during continuous operation.
