  • ColorTransparent
  • Handles 2000 psi at 150 °F for high-pressure systems
  • Rated 300 psi steam at 550 °F for heat-intensive lines
  • Seamless Schedule 80 steel eliminates weld leak paths
  • NPT male threads on both ends simplify installation

1 1/2 in Schedule 80 Steel Nipple

This 1 1/2 inch NPT pipe nipple is manufactured from seamless steel with a black finish. It is designed for air, natural gas, non-potable water, oil, and steam applications. The fitting meets Schedule 80 specifications for industrial piping systems.

2000 psi Maximum Operating Pressure

The nipple withstands 2000 psi at 150 Degrees F and 300 psi steam pressure at 550 Degrees F. This pressure rating determines suitability for high-pressure air, gas, oil, and steam lines. Builders needing higher pressure ratings must select a different class of fitting.

Seamless Construction and NPT Threads

The seamless steel construction eliminates welded seam leak paths under pressure. Male NPT threads on both ends allow direct connection to female NPT fittings without adapters. No gaskets, sealant, or additional hardware are included in the package.

Questions about this item

What does the 2000 psi rating mean when the nipple is installed in a live system?

It is the maximum operating pressure the steel nipple can handle at 150 °F, so the connected piping and components must also be rated for at least that pressure at the same temperature.

How does the NPT thread standard affect the seal in practice?

NPT threads are tapered, so tightening creates a metal-to-metal seal; use thread sealant or tape rated for the fluid and temperature to prevent leaks.

What clearance is needed to fit the 4 in overall length and 1 57/64 in outside diameter?

Allow at least 4 in of straight run for the nipple body plus room for a wrench on the 1 57/64 in hex area, and verify adjacent fittings clear the Schedule 80 wall thickness.
