1-1/2" No Lead Press x PEX F1807 Adapter

The Legend Valve 450-857P adapter connects a 1-1/2 inch press fitting to a PEX F1807 connection in potable water systems. It is intended for professional plumbers and qualified installers working on residential or commercial piping projects. The no lead construction meets requirements for drinking water applications. This component is not for buyers who need a different connection type or size.

Press installation with compatible tool

Installation requires a compatible press tool and the correct jaw size for the 1-1/2 inch press end. The PEX F1807 side uses a standard crimp ring or clamp method with the appropriate tool. Common issues include using an incorrect jaw, insufficient press force, or damaged tubing that prevents a proper seal. Always verify tool calibration and tubing condition before pressing.

No lead construction for potable water

The adapter handles typical residential and light commercial pressure and temperature ranges for hot and cold water distribution. The no lead brass body resists dezincification and corrosion in aggressive water conditions. It is not designed for gas, fuel oil, or high-temperature steam service. Installers should confirm local code acceptance for press fittings in the specific application.

Questions about this item

How can I confirm the 1-1/2" No Lead Press x PEX F1807 adapter is sealed correctly after pressing?

Perform a pressure test on the installed connection; a leak-free joint at system pressure confirms the press and F1807 PEX seal are working as intended.

What components come with the 450-857P adapter and what must be sourced separately?

The box contains the 1-1/2" No Lead Press x PEX F1807 adapter only; PEX tubing, press jaws, crimp rings and any required tools are sold separately.

Which version of the 450-857P should I choose for a no-lead press-to-F1807 transition?

The single listed version 450-857P is a 1-1/2" no-lead press-by-F1807 adapter; select it when you need that exact press-to-PEX transition.
