Black steel pipe nipple with threaded ends, 9 inches long

Value Brand

Value Brand 1" x 9" Black Steel Pipe Nipple Sch 40

SKU CH-9WB1-2KYYR

Schedule 40 black steel nipple threaded for air, gas, oil, steam or non-potable water at 300 psi

  • Schedule 40 rating supports 300 psi at 150 °F
  • 9-inch length fits standard plumbing runs
  • Welded steel construction resists cracking under pressure
  • Black coating protects against surface corrosion
  • Threaded male ends connect without extra fittings

Application & Use

This Schedule 40 black steel nipple connects threaded components in air, natural gas, non-potable water, oil and steam systems. The 1 inch nominal size and 9 inch overall length suit standard plumbing and industrial piping layouts. It is not for potable water lines or applications requiring galvanised or stainless steel corrosion resistance.

Pressure Rating

The fitting withstands 300 psi at 150 degrees F for general service and 150 psi at 350 degrees F for steam duty. These limits define whether the nipple matches the system design pressure and temperature. Installations exceeding either value need a higher-rated component.

Sustained Load Behaviour

Electric resistance welded construction maintains joint integrity under continuous pressure cycling and thermal expansion. The black steel finish offers no sacrificial corrosion protection, so prolonged exposure to moisture or aggressive fluids will degrade the wall thickness over time.

Questions about this item

How does the 1 inch nominal size translate to the actual outside diameter on this nipple?

The outside diameter measures 1 5/16 inches, so the 1 inch nominal size refers to the approximate inside diameter rather than the external dimension.

What does the Schedule 40 rating mean for the pressure this fitting can handle?

Schedule 40 indicates a maximum operating pressure of 300 psi at 150 degrees Fahrenheit and a maximum steam pressure of 150 psi at 350 degrees Fahrenheit.

What thread standard and length do I need to match for a leak-free joint?

Both ends use male NPT threads on a 9 inch overall length, compatible with standard Schedule 40 female fittings of the same nominal size.
