Product Identity
The Legend Valve 350-513 is a 6-inch black coupling designed for plumbing systems. It connects two female NPT threads in a straight line. This part suits installers joining pipe sections in residential or commercial water lines.
Critical Specification
The coupling measures 6 inches in overall length with female NPT threads on both ends. This dimension determines whether the fitting bridges the gap between your existing pipes. Verify the required spacing before ordering.
Operational Factors
The black finish provides standard corrosion resistance for typical indoor plumbing environments. No moving parts or electrical components are present, so noise and power draw are not applicable. The fitting handles normal water pressure without thermal concerns.

Questions about this item
What does the 6-inch length mean once the coupling is installed?
The 6-inch measurement is the overall length of the black coupling, so it occupies that much space between the two female NPT connections in your piping run.
How does the FNPT x FNPT thread standard affect what I can connect?
Both ends have female National Pipe Taper threads, so you must supply male NPT fittings or nipples to join this coupling to pipe or equipment.
What clearance or mounting features does the coupling need to fit?
It requires enough straight run to accommodate the 6-inch body plus the engagement length of the male threads you screw into each end.
