4" Schedule 40 Galvanized Nipple
This 4-inch galvanized nipple is built to Schedule 40 dimensions for standard plumbing connections. It suits installers joining two female-threaded fittings in water, gas or air lines. The E-Series designation identifies the Legend Valve product line.
Replacing Worn or Short Pipe Sections
Use this nipple when an existing threaded connection has corroded, cracked or been cut too short during a repair. The jump is worth it when the system pressure and media are compatible with galvanized steel and Schedule 40 wall thickness. It does not suit installations requiring stainless steel, brass or plastic piping materials.
Threaded Installation Basics
The nipple installs by threading into matching 4-inch female NPT fittings using pipe thread sealant or tape. Over-tightening can split the fitting or strip the threads, while under-tightening leaves a leak path. Always verify thread compatibility before assembly.

Questions about this item
What thread size does the 4-inch Schedule 40 galvanized nipple require for a watertight fit?
The nipple uses 4-inch NPT threads on both ends; wrap each male thread with PTFE tape or pipe dope before tightening into the matching female fitting.
Which installation step is most often missed when connecting this E-Series nipple?
Installers frequently forget to apply thread sealant to both ends before assembly, which leads to leaks once the system is pressurised.
How long before the galvanized coating on this 356-226E nipple typically needs replacement?
In normal water supply service the zinc coating lasts decades; replace the nipple only if you see white rust, pitting, or reduced flow from internal corrosion.
