2-1/2" NPT Steel Pipe Nipple 12

This 12-inch steel pipe nipple features 2-1/2 inch NPT threads on both ends for connecting threaded fittings in piping systems. It is manufactured from welded Grade B steel with a black finish and suits air, natural gas, non-potable water, oil, and steam applications. The fitting is rated for Class 150 compatibility and globally sourced.

Capacity and Pressure Ratings

The nipple handles a maximum operating pressure of 945 psi at 650 degrees F and a maximum steam pressure of 150 psi. Its operating temperature range spans from -20 degrees F to 600 degrees F, with gravity flow not supported. These limits define the headroom for high-pressure steam, hot oil, or compressed air lines.

Class 150 Fitting Compatibility

This nipple is built to Class 150 fitting standards, which determines whether it matches the pressure class of the valves, flanges, and fittings in the rest of the system. Mismatched classes can lead to leaks or failure at the joint. Verify the system's pressure class before installation.

Highlights

  • Steel construction rated for 945 psi working pressure
  • Handles steam service up to 150 psi at 650 °F
  • Welded Grade B steel resists vibration and shock

Questions about this item

Will the 2-1/2 inch NPT threads on this steel nipple match the Class 150 fittings already on my air and steam lines?

Yes. The nipple is built to Class 150 compatibility with NPT threads on both ends, so it threads directly into existing Class 150 fittings used for air, natural gas, non-potable water, oil and steam service.

How can I verify the nipple is holding pressure correctly after I install it?

Pressurise the system up to the rated limits — 945 psi at 650 °F for general service or 150 psi for steam — and check every joint for leaks; the welded steel construction and Grade B material are designed to maintain a tight seal across the full -20 °F to 600 °F operating range.

Does the 12-inch length come with any sealant, gaskets or protective caps, or do I need to buy those separately?

The box contains only the black-coated steel nipple itself; thread sealant, gaskets and protective caps are not included and must be purchased separately.
