Steel Pipe Nipple for Air and Fluid Lines

This BECK steel pipe nipple joins two female NPT threads in a straight run. It is manufactured in the USA from Grade B welded steel with a black anodised finish. The fitting handles air, gases, non-potable water and oils at a maximum operating pressure of 300 psi at 150 degrees F and a maximum steam pressure of 150 psi at 360 degrees F.

Suitable for Industrial Piping Builders

The 2 1/2 inch nominal pipe size and 4 inch overall length suit installers who need a short, rigid connector between existing threaded components. It is not intended for potable water systems and will not fit smaller or larger nominal pipe sizes without additional adapters.

Sustained Pressure Performance

Under continuous service the welded Grade B steel construction maintains its rated pressure limits without deformation. The black anodised coating resists corrosion from oils and non-potable water during extended exposure, while the NPT threads remain sealed through thermal cycles up to the rated steam temperature.

Questions about this item

What NPT thread size must the existing pipe or fitting have to connect this 2 1/2 in nipple?

The nipple has 2 1/2 in NPT threads on both ends, so the mating pipe or fitting must also be 2 1/2 in NPT.

Can this Grade B steel nipple handle the 150 psi steam pressure in my older boiler system?

Yes, it is rated for 150 psi steam at 360 Degrees F, matching that requirement.

How do I confirm the nipple is holding pressure after installation?

Pressurise the line up to 300 psi at 150 Degrees F and check for leaks at the threaded joints.
