Questions about this item

How does the 300 psi maximum operating pressure limit sustained use of this 3 in steel pipe nipple?

The fitting is rated for 300 psi at 150 °F, so continuous service must stay within that pressure and temperature envelope to avoid exceeding the design limit.

What heat or pressure conditions affect this nipple during all‑day operation?

It handles up to 300 psi at 150 °F for air, gases, non‑potable water or oils, and 150 psi at 360 °F for steam without degrading the black anodized steel body.

Which thread standard must the mating fittings match for this NPT nipple to seal properly?

Both ends use 3 in NPT threads, so any connecting pipe, valve or fitting must also be 3 in NPT to achieve a leak‑free joint.
