1" Press-Flange Adapter Valve

The Legend Valve 450-175P is a 1" press-by-flange adapter designed for plumbing installations. It provides a transition between press-fit piping and flanged equipment or fittings. The valve is supplied new and carries California Proposition 65 warnings for chemicals known to cause cancer and reproductive harm. Professional installers can use it to join dissimilar connection types in water or hydronic systems.

Suits Press-to-Flange Transitions

This adapter suits plumbers and contractors who need a direct 1" press-to-flange connection without additional couplings. It is not intended for installations that require a threaded, soldered or grooved joint at either end. Buyers who need a different nominal size, a press-by-press configuration or a flange-by-flange valve should look at other fittings. The product ships directly from the manufacturer.

1" Nominal Press-by-Flange Configuration

The defining specification is the 1" nominal size with a press connection on one side and a flange connection on the other. This exact combination determines whether the adapter matches the piping and equipment in the job. Verify the press-tool compatibility and flange bolt pattern against the project requirements before purchase. The model reference 450-175P identifies this specific configuration.

Questions about this item

How do I verify the 1" press-flange connection is sealing properly after installation?

Pressurise the line and inspect the press joint and flange face for any moisture; a dry joint with no weeping at the 1" connection confirms the adapter is working as intended.

What components are included with the 450-175P adapter and what must be sourced separately?

The box contains the 1" press-flange adapter valve only; press tools, flange gaskets, bolts and piping are not included and must be purchased separately.

Which Legend Valve press-flange adapter should I choose for a 1" nominal pipe size?

Select the 450-175P model — it is the 1" press-flange adapter in the Legend Valve range and matches a 1" nominal pipe size.
