Value Brand 3/4" MNPT x 18" TBE Black Pipe Sch 40

SKU CH-38NT-E0WM8

Schedule 40 black steel pipe, 18 in overall length with MNPT threads both ends, rated 150 psi at 150 °F and 1454 psi steam at 650 °F

  • 3/4" MNPT threads on both ends for direct fitting
  • 18" overall length suits standard plumbing runs
  • Schedule 40 wall rated to 150 psi at 150 °F
  • Black steel meets ASTM A-53 and A-733 standards
  • Electric resistance weld construction ensures joint integrity

3/4" MNPT Threaded Black Steel Pipe

This 18-inch Schedule 40 pipe connects with male NPT threads on both ends for standard plumbing assemblies. It is built from black steel with an electric-resistance weld for structural integrity. The pipe meets ASTM A-53, ASTM A-733 and Federal Specification WWN 351 for code-compliant installations.

150 psi Working Pressure at 150 °F

The pipe handles water, air or gas service up to 150 psi at 150 degrees Fahrenheit and steam duty up to 1454 psi at 650 degrees Fahrenheit. Its 7/64-inch wall and 13/16-inch inside diameter suit typical residential and light-commercial runs. Higher-pressure or larger-volume systems will require heavier-wall or larger-diameter pipe.

Fits Standard 3/4" NPT Fittings and Valves

Threaded ends accept off-the-shelf couplings, elbows, tees and valves without special tools or adapters. The 1 3/64-inch outside diameter clears common insulation and pipe hangers. Installers needing flanged, grooved or press-connect joints must choose a different connection type.

Questions about this item

Will this 3/4" MNPT x 18" black pipe thread into my existing galvanized fittings without leaks?

Yes, the MNPT threads on both ends follow standard taper specs so they seal properly with galvanized or black-iron fittings when you use pipe dope or PTFE tape.

How do I confirm the pipe is rated for my 150 psi compressed-air line after installation?

The pipe is stamped for 150 psi at 150 °F and meets ASTM A-53 and A-733; pressure-test the assembled line with soapy water to verify every joint holds.

Does the 18-inch length include the threaded portion, and are couplings or sealant supplied?

The 18 in overall length is measured end-to-end including threads; no couplings, nipples or thread sealant are in the box — buy those separately.
