Legend Valve 313-104NL Flare Union

The Legend Valve 313-104NL is a 3/4 inch T-4200NL no-lead bronze flare-by-flare union coupling. It joins two flare fittings in a three-part assembly designed for plumbing applications. The component meets no-lead material requirements for potable water systems. This coupling provides a straight connection between matching flare ends.

Suitable for flare-to-flare joints in water supply

Installers needing a no-lead bronze union for 3/4 inch flare connections will find this part appropriate. It is not intended for compression, sweat or threaded pipe ends. Buyers who require a different pipe size or connection method should select an alternative fitting. The Proposition 65 notice indicates the presence of listed chemicals.

Three-part union assembles with standard flare nuts

The union body separates to accept the flare nuts already fitted to the tubing. Tighten each nut to the flare seat using appropriate wrenches without over-torquing the bronze. A common issue is reusing deformed flare nuts that prevent a proper seal. Ensure the flare faces are clean and square before final tightening.

Questions about this item

What size flare fittings must I already have to connect this 3/4" T-4200NL union?

You need two 3/4-inch flare ends on the tubing or pipe you are joining so the union can thread onto both sides.

Will this no-lead bronze union corrode when paired with older copper flare nuts?

The no-lead bronze body is compatible with standard copper flare nuts, so it will not create a galvanic issue in typical plumbing installations.

How can I confirm the union is sealed correctly after I tighten both flare connections?

Pressurise the line and check each flare joint for leaks; a dry joint with no seepage shows the union is working as intended.
