Industrial Pipe Nipple for High-Pressure Systems

This 3-inch NPT threaded steel nipple connects piping in air, gas, oil, and non-potable water lines. It is built to Grade B specifications with a black anodized finish and welded construction for durability in industrial and commercial installations.

Sustained Pressure and Temperature Performance

The fitting handles a maximum operating pressure of 300 psi at 150 degrees Fahrenheit and a maximum steam pressure of 150 psi at 360 degrees Fahrenheit. Its welded steel body maintains structural integrity under continuous load without the deformation risk seen in lighter fittings.

Straightforward Threaded Installation

Standard NPT threads on both ends allow direct assembly into compatible female fittings using common pipe wrenches. Installers must apply appropriate thread sealant to prevent leaks and avoid over-tightening, which can crack the female port or distort the nipple threads.

Questions about this item

Does the pipe nipple generate noise, heat or consume power when installed in a system running continuously?

The Beck C. H. pipe nipple is a passive steel fitting with no moving parts, so it produces no noise, generates no heat and draws no power during continuous operation.

What existing pipework or fittings must already be in place for this 3 inch NPT nipple to connect?

You need mating 3 inch NPT female threads on both sides — such as threaded pipe, couplings, valves or equipment ports — to screw the nipple into.

Will the Grade B steel nipple rated for 300 psi at 150 °F work safely alongside older threaded components in the same line?

Yes, provided the older components also carry a 300 psi pressure rating at 150 °F and use compatible 3 inch NPT threads, the nipple will integrate without reducing the system’s pressure limit.
