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.

Should I choose the 4-inch by 12-inch size for my drainage setup?

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.
