Threaded no-lead cast bronze reducing coupling with female NPT ends

Legend Valve

Legend Valve 310-377NL 1-1/2" x 1/2" No Lead Reducing Coupling

SKU CH-FW10-CEX59

Reducing coupling joins 1-1/2" and 1/2" FNPT threads in no-lead cast bronze

  • No-lead construction reduces health risk
  • Cast bronze body resists corrosion
  • FNPT threads simplify pipe connections
  • Reducing design joins mismatched pipe sizes
  • Proposition 65 warning discloses regulated chemicals

Product identity

This Legend Valve 310-377NL reducing coupling connects 1-1/2 inch and 1/2 inch female NPT threads. The no-lead cast bronze body meets California Proposition 65 disclosure requirements for plumbing installations. It is a new fitting supplied for potable water and general fluid distribution systems.

Suitable applications and limits

The coupling suits installers joining two different pipe sizes in a straight run using threaded connections. It does not serve applications requiring a lead-free certification beyond the Proposition 65 notice, nor does it replace a union, elbow or tee where a change of direction or disassembly is needed. Buyers needing push-fit, compression or sweat ends should select a different fitting type.

Deciding specification

The FNPT x FNPT thread configuration is the single detail that determines whether this part matches the existing pipework. Both ends are female National Pipe Taper threads sized at 1-1/2 inch and 1/2 inch respectively. Verify the thread standard and diameters on the pipes before ordering.

Highlights

  • No-lead construction reduces health risk
  • Cast bronze body resists corrosion
  • FNPT threads simplify pipe connections
  • Reducing design joins mismatched pipe sizes
  • Proposition 65 warning discloses regulated chemicals

Questions about this item

What pipe thread size must I have on both sides to install the 1-1/2" x 1/2" reducing coupling?

The coupling uses FNPT threads on both ends, so you need matching 1-1/2 inch and 1/2 inch female NPT connections on your piping.

Will the no-lead cast bronze body resist corrosion if I connect it to older brass fittings in my system?

The no-lead cast bronze construction is compatible with existing brass components and resists dezincification in potable water applications.

How can I verify the 310-377NL coupling is sealed correctly after threading it onto my pipes?

Pressurise the line and check for leaks at both FNPT joints; a properly threaded and sealed coupling will hold pressure without weeping.
