Product Identity

The Legend Valve 313-105NL is a 1-inch flare-to-flare union designed for plumbing installations requiring a secure, no-lead bronze connection. It suits professional plumbers and maintenance teams working on potable water lines where lead-free compliance is mandatory.

Sustained Load Behaviour

The no-lead bronze body resists corrosion and scaling during continuous water flow, maintaining joint integrity under constant system pressure. The three-part flare design allows repeated disassembly without degrading the sealing faces, supporting long-term service cycles.

Upgrade Context

This union replaces older leaded-brass flare fittings in projects that must meet current no-lead regulations. The switch is justified when local codes prohibit leaded alloys or when system upgrades demand certified no-lead components for potable water safety.

Highlights

  • No-lead bronze protects drinking water safety
  • 1-inch flare union connects copper tubing reliably
  • Three-piece design allows easy disassembly
  • Legend Valve brand backs professional-grade quality
  • California Prop 65 warning discloses chemical hazards

Questions about this item

Does the 1" T-4200NL union generate any heat or noise during continuous water flow?

The all-bronze body has no moving parts, so it produces no noise and no heat beyond the water temperature itself.

What existing plumbing must be in place to install this flare-by-flare union?

You need two pipes already fitted with 1-inch flare nuts that match the union's flare seats.

Will this no-lead bronze union corrode when joined to older copper or brass fittings?

The no-lead bronze construction is compatible with standard copper and brass plumbing, preventing galvanic corrosion at the joint.
