Short black steel pipe nipple with threaded ends

Value Brand

Value Brand 1/4" MNPT x MNPT Black Pipe Nipple Schedule 40 2 1/2 in

SKU CH-M2VP-1B9ER

Schedule 40 steel nipple with 1/4 in MNPT threads for air, gas, oil or steam up to 300 psi at 150 °F

  • 1/4 in NPT threads connect to standard fittings
  • Schedule 40 steel withstands 300 psi at 150 °F
  • 2 1/2 in length fits tight piping runs
  • Black coating resists corrosion in air, gas, oil and steam systems
  • Electric resistance weld construction ensures leak-free joints

Application & Compatibility

This 1/4 inch nominal pipe size nipple connects air, natural gas, non-potable water, oil, or steam lines using Schedule 40 threaded fittings. It suits maintenance, repair, and new installations where black steel pipe is specified for these media.

Pressure Performance

The welded steel construction handles a maximum operating pressure of 300 psi at 150 degrees Fahrenheit and a maximum steam pressure of 150 psi at 350 degrees Fahrenheit. Electric resistance weld seams maintain integrity under these sustained thermal and mechanical loads.

Critical Specification

The overall length is 2 1/2 inches with an outside diameter of 17/32 inch, defining the exact space the fitting occupies between two female threaded ports. Buyers needing a different centre-to-centre dimension must select another length.

Questions about this item

Does the 1/4 in Schedule 40 steel nipple generate noticeable heat or noise when carrying steam at 150 psi continuously?

The nipple is a passive steel fitting with no moving parts, so it produces no noise and negligible heat of its own; the steam temperature of 350 °F will warm the pipe surface.

What thread sealant or tape is required to make the 1/4 in MNPT connections leak-free?

Standard PTFE tape or pipe-thread sealant rated for 300 psi at 150 °F is applied to the male NPT threads before tightening into the mating female ports.

Will the 17/32 in outside diameter and 2 1/2 in length match the spacing on my existing Schedule 40 black-iron header?

Yes, the nipple follows Schedule 40 dimensions, so its 17/32 in OD and 2 1/2 in overall length align with other Schedule 40 fittings of the same nominal size.
