Pipe Nipple for Air, Gases, Non-Potable Water, Oils

This 3-inch NPT steel nipple connects piping sections in industrial fluid systems. It suits maintenance crews and plant engineers who need a straight coupling for air, gases, non-potable water or oil lines. The welded Grade B steel construction provides a reliable joint for permanent installations.

Rated 300 psi at 150 Degrees F

The fitting holds 300 psi at 150 Degrees F for continuous liquid or gas service. Steam duty is limited to 150 psi at 360 Degrees F, so sustained high-temperature vapour lines must stay within that ceiling. Black anodized coating resists surface corrosion during extended exposure to the listed media.

Welded Grade B Steel with Black Anodized Finish

The 3 1/16 inch inside diameter matches nominal 3-inch pipe for consistent flow. Male NPT threads on both ends allow direct engagement with standard female fittings without adapters. Made in USA from welded steel, the nipple resists mechanical stress and vibration in fixed pipe runs.

Questions about this item

Does the 300 psi steel nipple get hot or noisy when it runs air or oil all day?

The nipple is a passive steel fitting with no moving parts, so it produces no noise and adds no heat beyond the fluid temperature.

What thread sealant or mating fittings do I need to install this 3 in NPT nipple?

You will need compatible 3 in NPT threaded fittings and an appropriate pipe thread sealant or tape rated for the 300 psi service pressure.

Will this Grade B welded nipple handle the 150 psi steam line I already have in the plant?

Yes, it is rated for 150 psi steam at 360 °F, matching your existing steam line specification.
