  • Galvanized coating resists corrosion for air, gas and non-potable water service
  • Schedule 40 welded steel construction rated to 150 psi at 150 °F
  • 3 in nominal size with 3 1/2 in outside diameter fits standard NPT threads
  • Made in USA from Grade B steel for consistent wall thickness
  • 3 1/16 in inside diameter maintains flow capacity in high-pressure lines

3-inch galvanised steel pipe nipple

This 3-inch nominal pipe size nipple is made from Grade B welded steel with a galvanised finish for corrosion resistance. It is rated for a maximum operating pressure of 150 psi at 150 degrees Fahrenheit. The fitting suits air, gases, non-potable water and oil applications in industrial or commercial plumbing systems. The part is manufactured in the USA and supplied new.

Check thread type and schedule before ordering

The nipple features 3-inch male NPT threads on one end and a 3-1/2-inch TBE connection on the other. Verify that your existing piping uses matching NPT threads and Schedule 40 wall thickness. Confirm the 3 1/16-inch inside diameter and 3-1/2-inch outside diameter align with your system requirements. Ensure the galvanised coating is compatible with the intended fluid and temperature range.

Replaces worn or corroded Schedule 40 nipples

Use this nipple to replace damaged galvanised steel fittings in the same nominal size and schedule. The upgrade is worth it when the existing nipple shows thread wear, internal corrosion or leakage at the rated 150 psi working pressure. It is not suited for potable water lines, steam service or systems requiring a different pressure class or material grade.

Questions about this item

What comes with the 3" MNPT x 3-1/2" TBE galvanized steel pipe nipple and what must be purchased separately?

The nipple is sold as a single fitting. Thread sealant or tape, plus any mating pipe, valves, or flanges required for the installation, are not included and must be bought separately.

How do I choose the correct Sch 40 nipple for my 3-inch nominal pipe system?

Match the nominal pipe size of 3 in, the Schedule 40 wall thickness, and the 3-1/2 in outside diameter to your existing piping. The 3-1/2 in TBE length and male NPT threads must also suit the connection points.

What does the 150 psi @ 150 °F rating mean when the nipple is installed in a real piping system?

It indicates the maximum non-shock working pressure for air, gases, non-potable water, or oils at temperatures up to 150 °F. System design must stay below this limit and account for pressure spikes or higher temperatures.
