  • Ready for air, gas, oil and non-potable water service
  • Schedule 40 steel rated to 300 psi at 150 °F

1/4" Schedule 40 Steel Pipe Nipple

This 1/4 inch nominal pipe size nipple connects two female-threaded components in air, gas, non-potable water or oil lines. The black coated steel construction uses electric resistance welding for structural integrity. It is manufactured to Schedule 40 dimensions for standard wall thickness.

Pressure Limits for Threaded Service

The fitting handles a maximum operating pressure of 300 psi at 150 degrees Fahrenheit for general fluid applications. Steam service is rated at 150 psi at 350 degrees Fahrenheit. These ratings define the safe envelope for the threaded Schedule 40 connection in typical plumbing or compressed air systems.

Welded Steel Build with Male Threads

The electric resistance welded seam provides a consistent bore through the 2 inch overall length. Male NPT threads on both ends allow direct engagement with female fittings without additional adapters. The black finish offers baseline corrosion resistance for industrial and mechanical installations.
