Black forged steel pipe coupling with threaded ends

Value Brand

Value Brand Black Forged Steel Coupling Class 3000

SKU CH-ZEM0-XX8CT

Black forged steel coupling rated to 3000 psi at 72 degrees F with FNPT connection

  • Forged steel construction withstands 3000 psi operating pressure
  • FNPT threaded connection meets ANSI B 1.20.1 standard
  • Black finish protects steel from corrosion exposure
  • ASME B 16.11 compliance ensures dimensional accuracy
  • ASTM A105 material rating verified at 72 degrees F

Application Suitability

This coupling suits piping systems that require a Class 3000 forged steel fitting with FNPT threads and a 1-1/2 inch pipe size. Installers working to ANSI B 1.20.1 or ASME B 16.11 standards can use it directly. It is not for systems needing a different pressure class, socket weld or butt weld ends, or a larger nominal bore.

Deciding Specification

The 3000 psi rating at 72 degrees F determines whether this fitting meets the design pressure of the system. Engineers must verify that the maximum operating pressure and temperature stay within this limit. If the service conditions exceed this pressure class, a higher-rated fitting must be selected instead.

Highlights

  • Forged steel construction withstands 3000 psi operating pressure
  • FNPT threaded connection meets ANSI B 1.20.1 standard
  • Black finish protects steel from corrosion exposure
  • ASME B 16.11 compliance ensures dimensional accuracy
  • ASTM A105 material rating verified at 72 degrees F

Questions about this item

What pipe size and thread type must my existing piping have to connect to this 1-1/2 in FNPT coupling?

Your piping must be 1-1/2 inch nominal size with male NPT threads matching the ANSI B 1.20.1 standard for a proper seal.

Will this Class 3000 forged steel coupling handle the pressure and temperature of my existing ASME B 16.11 system?

Yes, it meets ASME B 16.11 and ASTM A105 standards with a 3000 psi rating at 72 Degrees F for direct compatibility.

How can I verify the coupling is correctly installed and rated for my 3000 psi system?

Confirm the markings show Class 3000, ASTM A105, and ASME B 16.11, then pressure-test the joint to your system's working pressure.
