Steel Pipe Nipple for Industrial Piping

This 1 1/2 inch NPT steel nipple connects threaded components in air, gas, oil and non-potable water systems. The welded Grade B steel construction provides structural integrity for permanent installations. It is intended for maintenance crews and plant engineers who need a reliable threaded spacer.

300 psi Maximum Operating Pressure

The fitting is rated for 300 psi at 150 degrees Fahrenheit, which is the decisive figure for selecting this part. Steam service is limited to 150 psi at 360 degrees Fahrenheit. Verify that your system design pressure and temperature stay within these limits before installation.

Sustained Pressure and Temperature Performance

Under continuous operation the black anodized finish resists corrosion while the welded seam maintains its seal at the rated pressure. The 1 39/64 inch inside diameter keeps flow restriction low during extended duty cycles. The nipple performs steadily as long as operating conditions remain within the published pressure and temperature envelope.

Questions about this item

How does the 300 psi pressure rating hold up once the nipple is installed in a real piping system?

The nipple is rated for 300 psi at 150 degrees F for air, gases, non-potable water and oils, and 150 psi at 360 degrees F for steam service.

What does the NPT threading standard mean for sealing and compatibility with other fittings?

NPT tapered threads create a mechanical seal when tightened, and the 1 1/2 inch nominal size matches standard NPT fittings of the same designation.

What are the exact length and diameter dimensions I need to check for fit and mounting clearance?

The nipple measures 8 inches in overall length with a 1 1/2 inch nominal pipe size and an inside diameter of 1 39/64 inches.
