4 in NPT steel pipe nipple

This 4 inch nominal pipe size nipple connects NPT threads on both ends for air, gases, non-potable water and oils. The seamless steel body has a black anodised finish and is rated for 1,000 psi at 150 degrees F. It measures 6 inches overall length with a 4 1/2 inch outside diameter.

Threaded ends install with standard pipe tools

Apply compatible thread sealant or tape to the NPT connections before tightening to the required torque. Over-tightening can distort the threads and create leak paths, while under-tightening leaves the joint loose. The seamless construction reduces the risk of internal defects that cause failure under pressure.

Verify system pressure.

Confirm the 1,000 psi at 150 degrees F rating exceeds your maximum operating conditions and that steam service stays within 300 psi at 550 degrees F. Ensure the 4 inch nominal size matches the existing piping and that the black anodised steel is suitable for the fluid being conveyed. Buyers needing a different length, material or pressure class must select another fitting.

Questions about this item

How can I confirm the pipe nipple is holding pressure correctly after installation?

Pressurize the line up to 1,000 psi at 150 °F or 300 psi steam at 550 °F and check for leaks at the NPT threads; the seamless steel construction is rated for those limits.

What comes in the box and do I need to buy thread sealant or extra fittings separately?

The box contains the single 4 in NPT × NPT steel nipple, 6 in overall length, black anodized finish; thread sealant and any mating fittings are not included.

Which version of this nipple should I choose for a 4 in nominal pipe system rated at 1,000 psi?

Select the 4 in nominal size, 6 in overall length, seamless steel nipple with black anodized finish — it matches the 1,000 psi @ 150 °F rating for air, gases, non-potable water and oils.
