Black steel pipe nipple, 1 1/4 inch NPT threads, 3 inch length

Value Brand

Value Brand 1 1/4 in NPT Pipe Nipple 3 in Schedule 40 Steel

SKU CH-F4XE-DK0CJ

Schedule 40 steel nipple with NPT threads for air, gases, non-potable water and oils up to 300 psi

  • Male NPT threads connect to standard fittings
  • Schedule 40 steel wall handles 300 psi at 150 °F
  • 3 inch overall length fits tight assemblies
  • Electric resistance weld construction ensures joint integrity
  • Black coating protects carbon steel from corrosion

Product Purpose

The Value Brand 1 1/4 in NPT pipe nipple is a Schedule 40 steel fitting designed to join two female-threaded components in piping systems. It suits installers routing air, gases, non-potable water or oils at moderate pressure and temperature. Buyers needing potable-water certification or a different thread standard should look elsewhere.

Build and Connections

The nipple is manufactured from globally sourced steel with a black finish and electric-resistance-welded construction. Both ends carry male NPT threads, giving a 1 21/32 in outside diameter and an overall length of 3 in. The welded seam and Schedule 40 wall support a maximum operating pressure of 300 psi at 150 degrees F and a maximum steam pressure of 150 psi at 350 degrees F.

Upgrade Context

This fitting replaces a shorter nipple when additional spacing between components is required, or it upgrades from a lighter-wall alternative when the system demands Schedule 40 pressure ratings. The jump is worthwhile when the design calls for the 3 in length and the 300 psi rating at the stated temperature. It does not address needs for larger diameters, different thread types or potable-water approval.

Highlights

  • Male NPT threads connect to standard fittings
  • Schedule 40 steel wall handles 300 psi at 150 °F
  • 3 inch overall length fits tight assemblies
  • Electric resistance weld construction ensures joint integrity
  • Black coating protects carbon steel from corrosion

Questions about this item

What does the 300 psi rating at 150 °F cap for the NPT threads on this pipe nipple?

The 300 psi at 150 °F rating caps the maximum operating pressure for air, gases, non-potable water and oils through the 1 1/4 in NPT male threads.

What wall thickness does Schedule 40 require for a 1 1/4 in nominal pipe nipple?

Schedule 40 specifies the wall thickness for the 1 1/4 in nominal size, giving an outside diameter of 1 21/32 in on this 3 in nipple.

How do you seal the tapered NPT threads on this steel nipple, and what step is often missed?

Apply pipe-thread sealant or tape to the male NPT threads, then tighten; the step often missed is cleaning both male and female threads before sealing.
