Black steel pipe nipple with threaded male ends

Value Brand

Value Brand 1/2" MNPT x MNPT Black Pipe Nipple Schedule 40 8 in

SKU CH-Y4KN-492MQ

Connects air, gas, oil or non-potable water lines with a Schedule 40 steel nipple rated for 300 psi at 150°F and 150 psi steam at 350°F

  • Schedule 40 steel handles 300 psi at 150 °F
  • 8 in overall length fits standard 1/2 in NPT runs
  • Electric resistance weld gives consistent wall thickness
  • Black coating resists corrosion on air, gas, oil and non-potable water lines
  • Male NPT threads both ends install with common wrenches

Application & Suitability

This 1/2 inch Schedule 40 steel pipe nipple connects two female-threaded components in air, gas, non-potable water or oil lines. It is intended for installers who need a welded, black-coated nipple rated for 300 psi at 150 degrees F and 150 psi steam at 350 degrees F. Buyers who require potable-water approval or a different nominal size cannot use this fitting.

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. These ratings define the safe envelope for the intended fluids; exceeding either limit risks joint failure. The Schedule 40 wall thickness and electric-resistance weld construction support these figures within the stated temperature range.

Build & Daily Use

The nipple is manufactured from globally sourced steel with a black finish and measures 8 inches overall length with a 53/64 inch outside diameter. Male NPT threads on both ends allow direct engagement with standard Schedule 40 female fittings. The welded seam and coated surface resist corrosion in typical industrial environments, while the threaded ends enable straightforward assembly with pipe wrenches.

Highlights

  • Schedule 40 steel handles 300 psi at 150 °F
  • 8 in overall length fits standard 1/2 in NPT runs
  • Electric resistance weld gives consistent wall thickness
  • Black coating resists corrosion on air, gas, oil and non-potable water lines
  • Male NPT threads both ends install with common wrenches

Questions about this item

Should I choose the 8 in length or a different size for my Schedule 40 system?

Select the 8 in overall length when your piping layout requires that exact span between fittings; the 1/2 in nominal size and Schedule 40 wall match standard steel pipe dimensions.

What does the 300 psi rating mean once the nipple is installed in my air line?

The nipple will safely handle up to 300 psi at 150 °F for air, gases, non-potable water and oils, which is the maximum operating pressure for the welded steel construction.

How do the 1/2 in MNPT threads affect what I can connect to each end?

Both ends have 1/2 in male National Pipe Threads, so they screw directly into female-threaded Schedule 40 fittings, valves or equipment with the same thread standard.
