Purpose & fit

This 1 1/4 inch NPT steel pipe nipple connects threaded fittings in air, gas, non-potable water and oil lines. It suits installers who need a Schedule 40 welded nipple with male threads on both ends for standard plumbing or industrial assemblies.

Pressure & temperature limits

The fitting handles a maximum operating pressure of 300 psi at 150 degrees F and a maximum steam pressure of 150 psi at 350 degrees F. Its black coated steel construction and electric resistance weld meet the Schedule 40 rating for these service conditions.

Build & daily use

The globally sourced nipple measures 2 inches overall with an outside diameter of 1 21/32 inches and a welded seam. California Proposition 65 warnings apply for cancer and reproductive harm, so appropriate handling precautions are required during installation and maintenance.

Questions about this item

How do I install this 1 1/4" NPT steel nipple without damaging the Schedule 40 threads?

Wrap PTFE tape or apply pipe dope on the male NPT threads, then hand-tighten into the mating fitting before final tightening with a pipe wrench on the hex flats; the step often missed is using a second wrench to hold the adjoining fitting so the joint does not over-rotate and crack the electric-resistance-weld seam.

What maintenance or replacement will this black-coated steel nipple need over time?

Inspect the black finish annually for rust or scale; if corrosion appears on the 1 21/32 in outside diameter or at the welded seam, replace the nipple — no internal serviceable parts exist.

At what pressure limit does this 2-inch nipple reach its maximum rating during sustained use?

The maximum operating pressure is 300 psi at 150 °F for air, gases, non-potable water or oils; for steam service the limit drops to 150 psi at 350 °F.
