Legend Valve 313-155NL 1 T4351 No Lead Compression Union

SKU CH-56T1-S1YD8

No-lead bronze compression union joins two 1" CTS lines with a single fitting

  • No-lead bronze construction reduces lead exposure
  • Compression-to-compression design simplifies copper tube connections
  • 1-inch CTS sizing fits standard residential plumbing
  • T-4351NL model meets California Proposition 65 requirements
  • New condition ensures clean, undamaged threads and sealing surfaces

Application and Users

This Legend Valve 313-155NL union connects two 1-inch CTS compression lines in potable water systems. The no-lead bronze body meets low-lead requirements for drinking water installations. It suits plumbers and maintenance crews joining copper tube size piping without soldering.

Standard and Limits

The fitting uses compression ends on both sides for CTS tubing, creating a mechanical seal without heat. California Proposition 65 warnings apply because the bronze contains chemicals listed for cancer and reproductive harm. The joint is rated for typical residential and light commercial water pressure ranges.

Replacement Guidance

This union replaces a soldered copper coupling or a threaded adapter where disassembly may be needed later. The jump is worth it when future service access matters or when local code forbids leaded alloys. It does not suit applications requiring flare, push-fit or threaded connections.

Questions about this item

Which size of the Legend Valve 313-155NL no-lead compression union should I choose?

The 313-155NL model is a 1-inch T-4351NL no-lead bronze compression (CTS) by compression (CTS) union; choose this size when joining two 1-inch CTS pipes.

What does the "no lead" designation mean once the union is installed in a potable-water line?

The T-4351NL alloy meets no-lead requirements for drinking-water systems, reducing lead exposure at every joint.

What standard does the compression (CTS) interface follow, and what pipe sizes does it accept?

The compression ends follow CTS sizing, so each side accepts 1-inch copper tube size pipe for a direct, solder-free connection.
