The LEGEND VALVE 312-104nl is a lead-free bronze insert tee fitting designed for use in potable water and plumbing distribution systems. Insert tees connect copper or PEX tubing by sliding the barbed ends into the tubing and securing them with crimp rings or clamps, creating a reliable branch connection. This fitting is manufactured in bronze for corrosion resistance and durability in wet service environments. Its lead-free construction meets regulatory requirements for use in drinking water systems, making it appropriate for residential and light commercial plumbing installations. Licensed plumbers and pipefitters are the primary installers of this fitting type.
This insert tee is sized at 3/4 inch and is suited for branch connections in domestic hot and cold water supply lines. It is commonly installed in residential plumbing systems where a reliable, code-compliant branch point is needed on copper or flexible tubing runs. The lead-free bronze construction makes it suitable for potable water service wherever local codes require lead-free fittings in contact with drinking water.
Designed as an OEM-style replacement and standard insert fitting for 3/4 inch copper or PEX tubing in residential and light commercial potable water plumbing systems.
Installation should be performed by a licensed plumber in accordance with local plumbing codes and the IPC or applicable regional code. Shut off the water supply and depressurize the line before cutting into any existing pipe. Use the appropriate crimp or clamp tool rated for the tubing type and size. Inspect barbed ends and tubing for cuts or deformation before making the connection.
