3-inch Galvanized Steel Pipe Nipple

This 3-inch nominal pipe nipple is manufactured from Grade B steel with a galvanized finish for corrosion resistance. It features male NPT threads on one end and threads both ends for secure connections. The welded construction suits air, gas, non-potable water and oil lines in residential or commercial plumbing installations.

Schedule 40 Rating and 150 PSI Working Pressure

The Schedule 40 wall provides adequate wall thickness for standard pressure requirements up to 150 psi at 150 degrees Fahrenheit. Inside diameter measures 3 1/16 inches while the outside diameter is 3 1/2 inches. This rating covers typical low-pressure distribution but is not rated for steam service or higher-pressure hydraulic systems.

Made in USA Fitting for Direct Pipeline Integration

The nipple threads directly into compatible 3-inch NPT fittings without adapters, simplifying assembly in tight spaces. Its 5-inch overall length offers reach between fixed points while the galvanized coating protects exposed threads during installation. Buyers needing potable water certification or steam-rated components should select alternative products.

Questions about this item

Will the 3 in nominal pipe size and 3 1/2 in outside diameter match my existing Schedule 40 galvanized fittings?

Yes, the nipple follows Schedule 40 dimensions with a 3 in nominal size and 3 1/2 in outside diameter, so it threads into standard 3 in galvanized fittings.

How can I verify the 150 psi at 150 °F rating is holding after installation?

Pressurise the line to the working pressure, then inspect every threaded joint for leaks; a pressure gauge that remains steady at 150 psi confirms the rating.

Does the package include thread sealant or gaskets for the 3 1/16 in inside diameter?

The nipple ships alone; you must supply PTFE tape, pipe dope or a suitable gasket separately to seal the 3 1/16 in bore.
