Value Brand 1/8" x 12" Black Pipe Nipple Sch 40

SKU CH-W3W4-RQP9P

Schedule 40 black steel nipple with MNPT threads on both ends, 12 inches long, rated 300 psi at 150 degrees F

  • 1/8 inch nominal size fits standard plumbing threads
  • 12 inch overall length suits extended pipe runs
  • Schedule 40 wall thickness handles 300 psi water pressure
  • Black steel construction resists corrosion in wet environments
  • Electric resistance weld ensures consistent joint strength

1/8″ Schedule 40 Black Pipe Nipple

This 12-inch black steel nipple is threaded on both ends with male NPT connections. It is manufactured to Schedule 40 specifications using electric resistance welding for a consistent wall thickness of 1/16 inch. The fitting is designed for standard plumbing and piping installations.

Suitable for Low-Pressure Water, Gas and Steam Lines

It handles up to 300 psi at 150 °F and 150 psi saturated steam, making it appropriate for residential supply lines and light commercial piping. Builders needing higher pressure ratings, stainless steel construction or larger diameters should select a different fitting.

1/8″ Nominal Size with MNPT × MNPT Threads

The nominal bore is 1/8 inch with an outside diameter of 25/64 inch. Both ends feature male National Pipe Taper threads so the nipple joins two female-threaded components directly without additional adapters.

Questions about this item

What thread type must my existing fittings have to connect to the MNPT x MNPT ends?

The nipple has male NPT threads on both ends, so the mating fittings need female NPT threads of the same 1/8 in nominal size.

Will the 300 psi @ 150 Degrees F rating match the pressure in my current Schedule 40 black steel system?

Yes, the nipple is rated for 300 psi at 150 °F and 150 psi steam, which aligns with standard Schedule 40 black steel piping at that temperature.

How can I verify the wall thickness after installation?

The wall thickness is 1/16 in and the outside diameter is 25/64 in; you can confirm both with a caliper on the exposed section.
