Hex Bushing for Lead-Free Plumbing

The Legend Valve 310-500NL is a 2-1/2" by 2" threaded hex bushing made from no-lead cast bronze. It connects male and female NPT threads of different diameters in potable water systems. The fitting meets California Proposition 65 disclosure requirements for chemical content. Professional plumbers and maintenance crews use it to transition pipe sizes safely.

Sustained Pressure and Corrosion Resistance

Cast bronze construction handles continuous water pressure and resists dezincification better than standard brass alloys. The no-lead composition prevents lead leaching into drinking water over decades of service. Thread engagement remains tight through thermal cycling and vibration without the galling common in softer metals. Installers rely on the hex shoulders for reliable torque application during assembly.

Replaces Leaded Bushings in Potable Systems

This fitting upgrades older leaded bronze or brass bushings where codes now mandate lead-free materials for drinking water. The jump is worth it on any renovation or repair touching potable lines, especially in jurisdictions enforcing Proposition 65 or federal Reduction of Lead in Drinking Water Act limits. It is not suited for gas lines, high-temperature steam, or applications requiring flanged connections.

Questions about this item

How much heat does the 310-500NL hex bushing generate when installed in a hot-water line running all day?

The 310-500NL is a passive cast-bronze fitting with no moving parts or electrical components, so it produces no heat of its own; it simply conducts the temperature of the water flowing through it.

What pipe threads must I already have on the 2-1/2" and 2" lines to connect this bushing?

The bushing has male NPT on the 2-1/2" side and female NPT on the 2" side, so both pipes must carry matching NPT threads for a proper seal.

Will the no-lead bronze alloy in the 310-500NL corrode when joined to older leaded-brass fittings in my existing system?

The no-lead cast bronze is compatible with traditional brass and bronze plumbing alloys; standard thread sealant or tape prevents galvanic concerns when mixing old and new components.
