Legend Valve

Legend Valve 313-169NL 3/4 x 1 T4370NL IPS-COM x MIP Coupling

SKU CH-HHSM-QXEEP

Connects 3/4" IPS plastic pipe to 1" MIP thread with no-lead bronze construction

  • No-lead bronze construction for potable water safety
  • 3/4" x 1" sizing connects different pipe diameters
  • IPS compression to MIP threads joins PE to threaded systems
  • T-4370NL model identifies the certified coupling design
  • California Prop 65 listed for chemical transparency

Product Identity

The Legend Valve 313-169NL is a no-lead bronze coupling designed to join 3/4 inch IPS-compression pipe to 1 inch male NPT threads. It serves plumbers and maintenance crews who need a compliant transition fitting for potable water lines.

Interface Limits

The compression end accepts polyethylene pipe sized to IPS outside diameters while the threaded end matches standard male NPT connections. No-lead bronze construction satisfies California Proposition 65 requirements, though the product carries warnings for chemicals linked to cancer and reproductive harm.

Deciding Specification

The 3/4 x 1 inch T-4370NL size combination determines whether this coupling fits the specific pipe and thread diameters on the job. Buyers needing a different IPS-to-MPT step size or a non-compression joint will need another fitting.

Questions about this item

Which size coupling do I need for a 3/4-inch PE pipe and a 1-inch male NPT connection?

This coupling joins a 3/4-inch IPS PE pipe to a 1-inch male NPT thread, matching the 3/4 x 1 T-4370NL specification exactly.

How does the no-lead bronze body perform once installed in a potable water line?

The no-lead bronze construction meets low-lead requirements for drinking water systems and resists dezincification in continuous service.

What does the IPS-to-MIP interface mean for pressure rating and seal method?

The IPS compression end seals on the PE pipe OD while the MIP thread mates with a female NPT fitting; pressure rating follows the pipe and thread standards for the installed assembly.
