Legend Valve 460-805NL 1" NL F1807 PEX x Insert Adapter plumbing

1-inch NL F1807 PEX x Insert Adapter

This brass plumbing adapter connects a 1-inch F1807 PEX fitting to an insert connection. It is intended for installers working on potable-water or hydronic systems that use the F1807 crimp or clamp method. The no-lead construction meets current low-lead requirements for drinking-water applications.

Capacity and headroom

The single 1-inch nominal size handles typical residential and light-commercial flow rates for hot and cold distribution. It is not suited for larger-diameter mains or high-volume commercial loops that require fittings above 1 inch. The adapter provides a direct transition without additional couplings in compatible pipe runs.

Fit in a build

The F1807 end accepts standard crimp or clamp rings and PEX tubing, while the insert end presses into matching insert fittings or valves. No special tools beyond a calibrated crimp or clamp tool are required for the PEX side. The compact body keeps the joint profile short, leaving more room in tight stud bays or manifold cabinets.
