This 4-inch steel pipe nipple connects two female NPT threads in air, gas, non-potable water and oil lines. It is manufactured in the USA from Grade B steel with a welded construction and a black anodized finish. The fitting handles up to 300 psi at 150 degrees F and 150 psi steam at 360 degrees F.

This nipple suits installers who need a straight 4-inch NPT-to-NPT connector for the listed fluids and pressure range. It is not intended for potable water systems. Buyers who require a different nominal size, a different thread standard or a fitting rated for higher steam pressure should look at alternative products.

Questions about this item

What thread size must the existing fitting have to connect this 4 in NPT pipe nipple?

The nipple uses 4 in NPT threads on both ends, so the mating fitting must also be 4 in NPT for a proper seal.

Will the black anodized coating on this steel nipple resist corrosion when joined to older galvanized pipe?

The black anodized finish provides corrosion resistance, and the Grade B steel construction is compatible with standard galvanized NPT threads in air, gas, oil or non-potable water systems.

How can I verify the nipple is holding pressure after installation?

Pressurise the line up to the 300 psi rating at 150 Degrees F and check all joints for leaks; the welded steel construction should show no weeping at the rated pressure.
