1-1/2" Black Steel Pipe Nipple
This 1-1/2 inch nominal pipe size nipple is manufactured from Grade B steel with a black anodized finish. The welded construction is made in the USA and designed for use with air, gases, non-potable water, and oils. It provides a 4-inch length for connecting compatible fittings in plumbing systems.
Suited for standard pressure piping.
This component suits installers joining steel pipe runs in non-potable applications up to 300 psi at 150 degrees Fahrenheit. The inside diameter measures 1 39/64 inches. Buyers needing components certified for drinking water systems or different pressure ratings should look elsewhere.
Schedule 40 wall thickness defines pressure rating
The Sch 40 designation confirms the wall thickness required for the stated maximum operating pressure of 300 psi. This single specification determines compatibility with the intended piping schedule and ensures the fitting meets the necessary strength for the application.

Questions about this item
How do I install the 1-1/2" black steel nipple without damaging the 1 39/64" bore?
Clean threads, apply pipe-thread sealant to male ends only, hand-tighten then turn one to two full turns with a strap wrench on the hex flats — never clamp the welded barrel.
What maintenance or replacement will the black anodized coating need over time?
Inspect annually for coating wear at thread roots; if bare steel shows, replace the nipple — the welded Grade B body does not accept field recoating.
Which pressure limit is reached first during sustained 150 °F air service?
The 300 psi @ 150 °F rating governs; steam rating of 150 psi @ 360 °F does not apply to air or gas lines.
