Value Brand

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

SKU CH-AXRW-GFYEX

Schedule 40 black steel nipple with 1/8 inch NPT threads on both ends, rated to 300 psi at 150 degrees Fahrenheit

  • Black steel resists corrosion for long service life
  • Schedule 40 wall handles 300 psi at 150 °F
  • MNPT threads on both ends for standard connections
  • Electric-resistance weld gives consistent joint strength
  • 8-inch length suits tight plumbing runs

Black Steel Nipple for Threaded Piping

This Value Brand pipe nipple is a Schedule 40 fitting made from black steel. It measures 1/8 inch nominal size by 8 inches overall length with male NPT threads on both ends. The welded construction uses electric resistance weld for consistent wall thickness. It suits plumbing, hydraulic or compressed-air systems that require a short, rigid connector.

Threaded Ends and Pressure Rating Define Use

The MNPT x MNPT threads allow direct assembly into female-threaded fittings, valves or equipment without extra adapters. A maximum working pressure of 300 psi at 150 degrees F and a steam rating of 150 psi WSP set the safe operating envelope. The 1/16 inch wall and 25/64 inch outside diameter meet Schedule 40 dimensions for standard black steel piping.

Limits of Schedule 40 Black Steel Pipe

The 1/8 inch nominal bore restricts flow volume, so the nipple is not suited for high-capacity supply lines. Black steel offers no corrosion resistance; exposure to moisture or aggressive fluids will require protective coating or a different material. Threaded joints demand proper sealant and torque to prevent leaks at the rated pressures. The 8 inch fixed length cannot be adjusted on site.

Questions about this item

Will the Schedule 40 wall thickness of 1/16 in need replacement due to corrosion?

The 1/16 in wall thickness on this Schedule 40 black steel nipple resists typical water corrosion; lifespan depends on water chemistry and whether the system uses oxygen-scavenging treatment.

Does the 300 psi pressure rating at 150 °F limit sustained high-temperature use?

Yes, the 300 psi @ 150 °F rating is the design ceiling; steam service is further limited to 150 psi WSP, so sustained temperatures above 150 °F require derating.

Does the black steel finish radiate noticeable heat when hot water runs continuously?

The 25/64 in outside diameter and black steel surface will become warm to the touch during continuous hot-water flow, but the small mass limits total heat output.
