Product identity

The Legend Valve 311-207 is a 3" x 4-1/2" brass nipple coupling designed for plumbing installations. It is intended for installers and maintenance teams joining pipe sections in water-supply systems. The no-lead red brass construction meets current material requirements for potable-water use.

Upgrade context

This fitting replaces worn or corroded nipples in existing pipework and upgrades older leaded-brass components to a no-lead specification. The change is worth it when a system must comply with modern drinking-water standards or when a leak path has developed at a threaded joint.

Build integration

The nipple threads into standard NPT connections on both ends, requiring compatible pipe or fittings of matching thread size. It occupies minimal linear space between components and eliminates the need for separate adapters when connecting two female-threaded fittings. California Proposition 65 warnings apply.

Questions about this item

What thread size and length does the 311-207 nipple need to connect?

The nipple measures 3 inches by 4-1/2 inches and is made from no-lead red brass for potable water lines.

Which sealant works best when threading the 207 fitting into place?

Apply PTFE tape or pipe dope on the male threads, then tighten until snug; over-tightening can crack the brass body.

How often should the 311 coupling be inspected for dezincification?

Check annually for white powdery deposits or green staining; replace the nipple if the brass surface shows pitting or loss of wall thickness.
