Steel Pipe Nipple 3" NPTxNPT 9

The Beck C. H. steel pipe nipple provides a 3-inch NPT threaded connection for air, gases, non-potable water and oils. Its welded Grade B steel construction carries a black anodized finish and is rated for 300 psi at 150 degrees F.

Suitable for industrial piping up to 300 psi

Installers working with compatible fluids and pressures within the 300 psi rating will find this fitting matches the requirement. Systems demanding a higher pressure class or a different nominal size should select an alternative component.

Maximum operating pressure 300 psi at 150 degrees F

This pressure rating is the primary limit that determines whether the nipple fits the application. Verify the system design pressure against this figure before installation.

Questions about this item

Will the 3 in NPT threads on this nipple mate with my existing 3 in steel pipe and fittings?

The nipple has 3 in NPT threads on both ends and a 3 1/16 in inside diameter, matching standard 3 in steel pipe dimensions.

How can I confirm the black anodized finish is holding up after I thread it into my air line?

Check for a uniform dark coating without bare steel showing at the thread roots and verify no leaks at 300 psi working pressure.

Does the box include thread sealant or gaskets for the NPT connections?

Only the 9 in steel nipple is supplied; pipe thread sealant or tape must be purchased separately.
