Short black steel pipe nipple with threaded ends

Legend Valve

Legend Valve 355-227E 4" x 4-1/2" Schedule 40 Black Nipple

SKU CH-HBRD-ZSXP6

A 4-inch Schedule 40 black nipple measuring 4-1/2 inches long for plumbing connections

  • Schedule 40 wall thickness handles high-pressure systems
  • 4-inch by 4-1/2-inch length fits standard pipe runs
  • Black steel construction resists corrosion in water lines
  • Legend Valve brand trusted by plumbing professionals
  • Proposition 65 warning informs safe handling practices

Application scope

This Legend Valve black nipple is a Schedule 40 pipe fitting used to join two female-threaded components in plumbing systems. It suits installers who need a standard-weight steel nipple for water, gas or oil lines in residential and light commercial work. The 4 inch nominal size and 4-1/2 inch length fit typical piping layouts.

Who should choose another fitting

This nipple is not intended for systems that require a heavier wall thickness than Schedule 40 provides. It is also unsuitable for installations where black steel is incompatible with the fluid carried or where local codes mandate a different material or coating. Buyers needing other lengths or diameters must select a different part number.

Deciding specification

The critical specification is the Schedule 40 wall thickness combined with the 4 inch nominal diameter and 4-1/2 inch overall length. Match these three figures exactly to the piping design; any deviation in schedule, size or length means this nipple will not fit the assembly.

Questions about this item

Will this 355-227E nipple thread onto my existing Schedule 40 black iron pipe without leaks?

Yes, the 355-227E is a Schedule 40 black nipple with standard NPT threads on both ends, so it mates directly with any Schedule 40 black iron pipe or fitting of the same nominal size.

How can I confirm the 4-1/2 inch length is correct once the nipple is installed between two fittings?

Measure the exposed length between the engaged threads after assembly; the distance from shoulder to shoulder should read 4-1/2 inches when both ends are fully tightened.

Does the 355-227E come with thread sealant or do I need to buy pipe dope and Teflon tape separately?

The nipple is supplied as a bare fitting only; you must purchase pipe thread sealant or Teflon tape separately to make a watertight joint.
