  • ColorTransparent
  • 4 in NPT threads connect steel piping securely

  • Black anodized finish resists corrosion on air, gas, oil lines
  • Welded construction rated for 150 psi steam at 360 °F

Application Scope

This Beck steel pipe nipple handles air, gases, non-potable water and oils in industrial piping runs. The Grade B welded construction suits fluid-transfer systems that require a 4-inch nominal bore and NPT threads on both ends.

Pressure and Temperature Limits

The fitting is rated for 300 psi at 150 degrees F for general service and 150 psi at 360 degrees F for steam duty. No minimum operating temperature or maximum operating temperature is specified, so the installer must verify suitability for any sub-zero or high-heat conditions.

Critical Sizing Parameter

The inside diameter measures 4 1/64 inches, which determines flow capacity and mating compatibility with other 4-inch schedule components. Buyers who need a different bore or a longer nipple length must select another part.

Questions about this item

Which length should I choose for a 4-inch NPT pipe nipple?

This nipple is 8 inches long with a 4-inch nominal pipe size, so select it when your layout requires that exact centre-to-centre distance.

What does the 300 psi rating mean once the nipple is installed?

It indicates the maximum non-shock operating pressure at 150 °F for air, gases, non-potable water or oils; do not exceed 300 psi in service.

How do the NPT threads affect what I can connect?

Both ends have 4-inch NPT threads, so they mate with any matching NPT fittings, valves or equipment rated for the same pressure and temperature limits.
