  • Schedule 40 steel handles 300 psi at 150 °F
  • Black coating suits air, gas, oil, steam and non-potable water

1-1/2" Schedule 40 Black Steel Pipe Nipple

This close-threaded nipple is manufactured from black steel with an electric resistance weld. It conforms to Schedule 40 dimensions and carries a nominal pipe size of 1-1/2 inches. The fitting is designed for use with air, natural gas, non-potable water, oil, and steam applications. It is globally sourced and supplied new.

Upgrades From Worn Or Leaking Threaded Connections

Replacing a damaged nipple restores the pressure integrity of a Schedule 40 system rated for 300 psi at 150 degrees Fahrenheit. The jump is worth it when the existing fitting shows corrosion, thread deformation, or leakage at the joint. A new welded steel nipple eliminates the failure point without changing the pipe schedule or nominal size.

Suits Installers Maintaining Existing Black Steel

This component suits plumbers and maintenance crews joining female-threaded fittings in compatible Schedule 40 networks. It is not intended for potable water lines due to Proposition 65 chemical warnings. Builders requiring a longer overall length or a different nominal diameter should select an alternative fitting.

Questions about this item

What thread size matches the 1-1/2 inch Schedule 40 close nipple?

The nipple uses 1-1/2 inch NPT threads on both ends, matching Schedule 40 fittings with the same nominal size.

Which step is often missed when sealing the tapered threads?

Apply PTFE tape or pipe dope clockwise on the male threads only, then tighten two full turns past hand-tight to avoid leaks.

When should the steel nipple be inspected or replaced in a steam line?

Check for corrosion, scale buildup, or thread deformation each time the system is opened; replace if wall loss or cracking is visible.
