3-inch Galvanized Steel Pipe Nipple

This 3-inch nominal pipe size nipple is made from Grade B welded steel with a galvanized finish for corrosion resistance. It features male NPT threads on one end and threaded both ends for standard pipe connections. The fitting is rated for 150 psi at 150 degrees Fahrenheit and suits air, gases, non-potable water, and oils.

Verify Thread Type and Pressure Rating

Confirm your existing piping uses male NPT threads and matches the 3-inch nominal size before ordering. Ensure the system operating pressure does not exceed 150 psi at the maximum temperature rating. This nipple is not intended for potable water or steam service and carries no steam pressure rating.

Connects Standard Iron Pipe Systems

The nipple joins two female-threaded fittings in a rigid steel pipeline without requiring additional adapters. Its welded construction and galvanized coating provide durability in industrial or commercial plumbing installations. The 8-inch overall length spans the gap between fixed components while maintaining a 3 1/16-inch inside diameter for flow.

Questions about this item

Does the galvanized steel nipple ship with thread sealant or gaskets included?

The nipple is supplied as a single Sch 40 steel piece with male NPT threads on both ends; sealant tape, pipe dope or gaskets must be purchased separately.

Which schedule rating should I select for a 150 psi air line at 150 °F?

The listed Schedule 40 rating matches the 150 psi maximum operating pressure at 150 °F, so this nipple meets that requirement.

How does the 3 1/16 in inside diameter affect flow in a 3 in nominal pipe run?

The 3 1/16 in bore provides a full Schedule 40 flow area, keeping pressure drop consistent with standard 3 in steel piping at the rated 150 psi.
