SKU CH-CDRG-1QMQA

Steel pipe nipple with threaded NPT ends for air, gases, non-potable water and oils

  • Durable steel construction resists wear and corrosion
  • Handles air, gases, non-potable water and oils
  • Rated 300 psi at 150 °F for demanding systems
  • Electric-resistance weld ensures strong leak-free joints
  • Schedule 40 compatibility fits standard piping installations

Industrial Pipe Fitting

This steel pipe nipple connects threaded components in air, gas, non-potable water and oil lines. It suits maintenance crews and plant engineers who need a reliable Schedule 40 joint for moderate-pressure systems.

Welded Construction

Electric resistance welding creates a continuous seam that resists leakage under vibration. The black coating provides basic corrosion protection during storage and initial installation.

Male NPT Threads

Both ends feature 1 1/2 inch male National Pipe Threads for direct engagement with female fittings. The 8 inch overall length spans typical gaps between valves, regulators or equipment ports. Rated for 300 psi at 150 degrees F and 150 psi steam at 350 degrees F. Not for potable water service.

Questions about this item

How often will the 1 1/2 in Schedule 40 steel nipple need replacement in a 300 psi air system?

The welded steel nipple is rated for 300 psi at 150 °F; replacement depends on corrosion rate and inspection schedule rather than a fixed interval.

What pressure limit is reached first when the line runs continuously at 350 °F?

Steam service is limited to 150 psi at 350 °F, which is lower than the 300 psi air rating at 150 °F.

Does the black-coated 8 in nipple radiate noticeable heat or noise during all-day steam flow?

The steel body conducts heat from 350 °F steam, so the surface becomes very hot; the nipple itself has no moving parts and generates no noise.
