1/4 Inch x 2 Inch Black Steel Pipe Nipple – Threaded Schedule 40

The 1/4" x 2" Black Steel Nipple is a Schedule 40 threaded pipe segment used for joining female-threaded components in steam, air, gas, and oil systems. Manufactured from welded black steel pipe, it is designed for use in non-potable pressure applications requiring strength, durability, and corrosion resistance in low-moisture environments.

Product Features

  • Threaded Ends – Machined with NPT (National Pipe Taper) threads on both ends for direct compatibility with standard fittings.
  • Schedule 40 Wall Thickness – Provides sufficient pressure capacity for use in industrial and mechanical systems.
  • Carbon Steel Construction – Black finish resists scaling and oxidation; suitable for dry systems and fuel gas lines.
  • Consistent Cut Length – Precision-cut to nominal 2-inch length for alignment in compact assemblies or short extensions.

Technical Specifications

  • Material: Welded carbon steel (black-coated)
  • Nominal Size: 1/4 inch
  • Length: 2 inches (end-to-end including thread length)
  • Thread Type: NPT (ANSI B1.20.1)
  • Wall Thickness: Schedule 40
  • Compliance: ASTM A53 / ASTM A733 (dimensions and threading)

Common Applications

Frequently used in commercial and industrial piping systems, this nipple is suited for:

  • Steam and condensate return lines
  • Fuel oil or gas burner lines
  • Compressed air systems
  • Low-pressure water lines in heating loops (non-potable)

Installation Notes

Apply appropriate thread sealant or PTFE tape to male threads before installation. Avoid over-tightening, which may result in thread galling or stress cracking. Not intended for use in potable water systems or applications involving high corrosion exposure.

The 1/4" x 2" Black Steel Pipe Nipple offers a reliable and mechanically sound solution for short-distance threaded connections in pressure-rated mechanical systems.
