Installers needing a 3 in NPT threaded connector

The nipple suits maintenance crews joining steel pipe runs where welded construction and Grade B material are specified. It is not intended for potable water service or applications requiring a different nominal size or pressure rating. Buyers who need a larger bore or alternative thread standard should look at other fittings.

The product is a single steel nipple with NPT threads on both ends. No gaskets, sealant, brackets or additional hardware are included in the package. Installers must supply their own thread compound and any required mounting accessories.

Questions about this item

What thread standard must the mating fittings use to connect to this NPT nipple?

Both ends are cut to NPT taper threads, so any NPT-compatible fitting — valve, coupling or another nipple — will seal correctly.

Will this Grade B steel nipple handle the 300 psi air pressure my existing system runs at 150 °F?

Yes, the maximum operating pressure is rated at 300 psi at 150 °F, matching your current conditions.

How can I confirm the nipple is installed without leaks after assembly?

Pressurise the line to its working pressure, then check every joint with leak-detection fluid or soapy water for bubbles.
