SKU CH-E7G7-26MBS

Steel pipe nipple with 1/4 in NPT threads, 5 1/2 in long, rated 300 psi at 150°F for air, gases, non-potable water and oils

  • Black-coated steel resists corrosion in air, gas, oil and non-potable water service
  • Schedule 40 wall handles 300 psi at 150 °F and 150 psi steam at 350 °F
  • 1/4 NPT male threads on both ends connect directly to matching fittings
  • Electric-resistance welded construction ensures consistent wall thickness
  • 5 1/2 in overall length fits standard piping runs

Application Range

This steel pipe nipple handles air, gases, non-potable water, and oils. It is rated for a maximum operating pressure of 300 psi at 150 degrees F and a maximum steam pressure of 150 psi at 350 degrees F. The Schedule 40 wall provides standard strength for these services.

Connection Details

Both ends feature male NPT threads sized at 1/4 inch for direct installation into compatible fittings. The electric resistance welded construction ensures a consistent seam along the 5 1/2 inch overall length. A black finish coats the 1 7/32 inch outside diameter.

Limitations

The fitting is not suitable for potable water systems due to material composition. California Proposition 65 warnings apply for cancer and reproductive harm. Buyers needing different lengths, diameters, or thread standards must select alternative products.

Questions about this item

Will the black coating on this steel nipple need reapplication after long exposure to air or oils?

The black finish is a factory coating on the steel body; it is not a maintenance item and does not require scheduled reapplication under normal service.

At what pressure does the Schedule 40 rating reach its limit with 150 °F non-potable water?

The maximum operating pressure is 300 psi at 150 °F, which is the design limit for this Schedule 40 nipple.

Does the welded seam generate extra heat or vibration when fluid runs continuously at 300 psi?

The electric-resistance weld is a static joint; it adds no moving parts, so continuous flow produces no additional heat or vibration beyond the fluid itself.
