2" Black Steel Pipe Nipple

The Beck 2" MNPT x MNPT black steel pipe nipple is a Schedule 40 fitting manufactured in the USA from Grade B steel. It is designed for connecting two female-threaded components in piping systems handling air, gases, non-potable water, or oils. This new component suits installers needing a durable, welded conduit for fluid transfer.

Pressure and Temperature Limits

The nipple withstands a maximum operating pressure of 300 psi at 150 degrees F and a maximum steam pressure of 150 psi at 360 degrees F. These ratings define the safe envelope for the intended media. Systems exceeding these pressure or temperature thresholds require a different class of fitting not covered by this product.

Welded Construction and Threading

The black anodized finish protects the welded steel body, while the MNPT threads on both ends allow direct engagement with compatible female fittings. The 2 1/16 inch inside diameter maintains flow consistency for the nominal 2 inch pipe size. Installers should verify thread compatibility and chemical resistance for the specific application media.

Questions about this item

Should I choose the 2-inch nominal size or a different diameter for my plumbing system?

Select the 2-inch nominal pipe size when your system uses 2-inch fittings; the nipple's 2 1/16-inch inside diameter matches Schedule 40 dimensions for that size.

What does the 300 psi pressure rating mean when the nipple is installed in a working line?

The nipple withstands up to 300 psi at 150 °F for air, gases, non-potable water or oils, and 150 psi at 360 °F for steam service.

How do the MNPT threads affect what I can connect to this nipple?

Both ends have male NPT threads, so the nipple joins two female NPT fittings such as couplings, elbows or valves in the same 2-inch size.
