3/8" NPT Steel Pipe Nipple 6

This 3/8 inch NPT steel pipe nipple suits plumbers and maintenance technicians joining threaded pipe runs. The seamless construction handles air, gases, non-potable water and oils up to 2,000 psi at 150 degrees Fahrenheit. Steam service is rated to 300 psi at 550 degrees Fahrenheit.

Black anodized finish and seamless build

The black anodized coating protects the steel surface during storage and installation. Seamless manufacturing removes a welded seam that could leak under pressure. These attributes support the listed pressure and temperature ratings for the intended fluid types.

Verify thread size and system pressure

Confirm the existing piping uses 3/8 inch NPT threads before ordering. Ensure the system operating pressure and temperature stay within the 2,000 psi at 150 degrees Fahrenheit limit for liquids and 300 psi at 550 degrees Fahrenheit for steam. This item is restricted from sale in certain states.

Questions about this item

Will the black anodized coating on this 3/8" NPT steel nipple need replacement or maintenance over time?

The black anodized finish protects the seamless steel body from corrosion in air, gas, oil and non-potable water service; no recoating is required unless mechanical damage exposes bare metal.

What pressure limit will be reached first when this nipple runs continuously at 150 °F?

At 150 °F the maximum operating pressure is 2,000 psi, while the steam rating is 300 psi at 550 °F, so the 2,000 psi air, gas, oil and water limit governs first.

How much heat does this 6-inch nipple radiate during all-day operation at 2,000 psi?

Steel conducts heat from the flowing fluid, so the nipple will assume the fluid temperature up to the 150 °F operating limit; no internal heat is generated by the fitting itself.
