1/8 in Schedule 40 Black Steel Nipple

This 4-inch pipe nipple connects two female-threaded fittings in air, gas, oil or non-potable water lines. It is made from welded steel with a black finish and carries a 300 psi rating at 150 degrees Fahrenheit. The male NPT threads on both ends match Schedule 40 components.

Pressure and temperature limits

The fitting handles up to 300 psi for liquid or gas service at 150 degrees Fahrenheit. Steam duty is limited to 150 psi at 350 degrees Fahrenheit. These ratings define the safe operating envelope for the Schedule 40 wall thickness.

Welded steel construction and threading

Electric resistance welding forms the pipe body, giving a consistent seam for the rated pressures. Male NPT threads on each end allow direct engagement with Schedule 40 couplings, valves or equipment ports. The black coating provides basic corrosion resistance during handling and installation.

Questions about this item

Should I pick the 4 in length or a different size for my Schedule 40 system?

This nipple is 4 in overall length with a 1/8 in nominal pipe size and 13/32 in outside diameter; choose the length that matches your required pipe run between fittings.

What does the 300 psi rating mean when the line is at 150 °F?

The fitting is rated for a maximum operating pressure of 300 psi at 150 Degrees F, so it will hold that pressure at that temperature in air, gas, oil or non-potable water service.

How do the 1/8 MNPT threads limit what I can connect?

Both ends are 1/8 in male NPT threads, so they only mate with female NPT ports or couplings of the same nominal size and thread standard.
