Galvanised steel nipple pipe with threaded ends

Legend Valve 356-231E 4" X 7" Galvanized Nipple tubing

SKU CH-CS8G-M4GF4

Galvanized steel Schedule 40 nipple connects 4-inch pipes across a 7-inch length for plumbing systems

  • Schedule 40 wall thickness supports high-pressure plumbing
  • Galvanised coating resists corrosion in water systems
  • E-Series nipple design ensures standard thread compatibility
  • 4-inch by 7-inch dimensions fit common pipe runs
  • Proposition 65 notice flags regulated chemical content

Product Identity

The Legend Valve 356-231E is a Schedule 40 galvanized nipple measuring 4 inches by 7 inches. It serves plumbers and maintenance crews who need a short, threaded connector for water or gas distribution systems. The E-Series designation marks it as a standard fitting for joining two female-threaded components in residential or light commercial pipework.

Build Integration

The nipple threads directly into existing female fittings, requiring only thread sealant or tape to complete a joint. Its galvanized coating resists corrosion in potable water lines, while the Schedule 40 wall thickness handles typical municipal pressure without additional reinforcement. The fixed length closes a precise gap between elbows, tees or valves, freeing the installer from cutting and threading pipe on site.

Upgrade Context

This fitting replaces a corroded, leaking or undersized nipple in an existing galvanized network. The jump is worth it when the old piece shows mineral buildup, thread damage or rust-through that compromises flow or seal integrity. It is not suited for systems that require dielectric unions to separate dissimilar metals, nor for high-temperature steam lines where galvanizing can degrade.

Condition Note

The item is supplied new and carries California Proposition 65 warnings for chemicals known to cause cancer and reproductive harm. Installers should follow local code requirements for protective equipment and disposal of removed fittings.

Questions about this item

How does the Schedule 40 wall thickness hold up under sustained pressure?

The Schedule 40 galvanised steel wall provides the standard pressure rating for this nipple size, maintaining integrity under continuous system pressure.

Does the galvanised coating affect heat transfer or noise in a hot-water loop running all day?

The zinc coating adds negligible thermal resistance and produces no audible noise; the nipple behaves like standard steel pipe in a circulating hot-water system.

What pipe threads must the existing system have for this 356-231E nipple to connect directly?

Both ends are cut to standard NPT dimensions, so the mating fittings or pipes must carry matching National Pipe Taper threads.
