Two-inch by one-inch threaded bronze reducing coupling, no-lead cast finish

Legend Valve

Legend Valve 310-383NL 2" x 1" No Lead Reducing Coupling

SKU CH-7GNK-PWKJC

No-lead cast bronze reducing coupling connects 2-inch to 1-inch FNPT threads for potable water systems

  • No-lead bronze protects drinking water safety
  • 2" x 1" FNPT threads simplify pipe transitions
  • Cast bronze construction resists corrosion long-term
  • California Prop 65 listed for chemical awareness
  • Model 310-383NL ensures correct part identification

2" x 1" No Lead Reducing Coupling

The Legend Valve 310-383NL is a threaded cast bronze reducing coupling with FNPT x FNPT connections. It joins a 2 inch pipe to a 1 inch pipe in potable water or hydronic systems. The no-lead construction satisfies regulations for drinking water installations.

California Proposition 65 Compliance

This product carries two California Proposition 65 warnings for chemicals known to cause cancer and birth defects or other reproductive harm. The warnings inform installers and end users about regulated substances present in the bronze alloy. They do not change the fitting's mechanical function or its no-lead certification for potable water use.

Threaded FNPT Connection Limits

The FNPT x FNPT threads require pipe dope or tape to seal reliably under pressure. Cast bronze resists corrosion but can seize if dissimilar metals are threaded directly without dielectric isolation. The reducing step creates a flow restriction that must be accounted for in system pressure-drop calculations.

Questions about this item

How often should the cast bronze threads be inspected or replaced in a potable water system?

The no-lead cast bronze body resists corrosion, so threads typically need inspection only during routine plumbing maintenance or if a leak appears at the joint.

What pressure or temperature limit is reached first during continuous hot-water circulation?

The coupling is rated for standard plumbing pressures and temperatures; the bronze material handles typical hot-water loops without deforming.

Does the fitting generate noise, heat or extra power draw when water runs all day?

As a passive threaded fitting it adds no noise, heat or electrical load; flow noise depends on the piping system, not the coupling itself.
