  • Black steel construction resists corrosion

  • Threaded ends connect to air, gas, oil or steam lines
  • Electric resistance weld ensures leak-tight joints
  • Prop 65 notice flags chemical exposure risk

Pipe nipple for air, gas

This black steel nipple connects threaded pipe in air, natural gas, non-potable water, oil and steam lines. It is built to Schedule 40 dimensions with a 3/8 inch nominal size and an overall length of 3 1/2 inches. The electric resistance welded construction suits standard industrial and commercial plumbing installations. The product carries a California Proposition 65 warning for cancer and reproductive harm.

Pressure and temperature ratings for normal service

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. Black steel finish provides the standard surface for these service conditions. Threaded ends allow direct assembly into compatible Schedule 40 components without additional preparation.

3/8 inch Schedule 40 thread compatibility decides

The nipple matches only Schedule 40 threaded fittings and pipe of the same nominal size. It will not seal on other schedules or connection types. Verify the existing system uses Schedule 40 threads before ordering.

Questions about this item

How do I install the 3/8-inch Schedule 40 black pipe nipple without damaging the threads?

Apply pipe-thread sealant or tape to the male threads, then hand-tighten into the Schedule 40 fitting before final tightening with a wrench; over-torquing the 43/64-inch outside diameter can crack the female port.

What maintenance or replacement will the welded steel nipple need over time?

Inspect the electric-resistance weld seam and black coating periodically for rust or scale; replace the nipple if corrosion reduces wall thickness or if leaks appear at the threaded ends.

What pressure or temperature limit will be reached first during continuous steam service?

The 150 psi steam rating at 350 °F is lower than the 300 psi water rating at 150 °F, so the steam limit governs sustained steam applications.
