4-Inch Black Steel Pipe Nipple
This 4-inch nominal pipe size nipple is made from Grade B steel with a black anodized finish. It is manufactured in the USA and features welded construction. The component suits installers working with air, gases, non-potable water, or oils in industrial or commercial piping systems.
Schedule 40 Pressure Limits
The nipple handles a maximum operating pressure of 300 psi at 150 degrees Fahrenheit. For steam service the limit is 150 psi at 360 degrees Fahrenheit. These ratings define the practical envelope for any system using this Schedule 40 fitting.
Threaded Installation Notes
The pipe nipple uses standard tapered threads for joining to compatible fittings. Correct thread engagement and sealant prevent leaks at the rated pressures. Over-tightening can distort the welded seam or strip threads, so installers should follow normal pipe-fitting practice.

Questions about this item
Should I choose the 4-inch by 12-inch size for my drainage setup?
The 4-inch nominal size and 12-inch length suit standard drainage runs; verify your system uses 4-inch nominal pipe before ordering.
What does the 300 psi pressure rating mean once the nipple is installed?
It indicates the nipple can handle up to 300 psi at 150 degrees Fahrenheit for air, gases, non-potable water or oils in normal service.
Does the Schedule 40 rating cap the flow or pressure I can run through it?
Schedule 40 defines the wall thickness; the 300 psi at 150 degrees Fahrenheit rating is the practical pressure limit for this nipple.
