Value Brand 1MNA8 Black Forged Steel Coupling Class 3000

SKU CH-3EFK-ZNCXE

A 2-inch FNPT forged steel coupling rated to 3000 psi at 72 degrees F and built to ANSI B1.20.1, ASME B16.11 and SA105/ASTM A105 standards

  • Forged steel construction withstands 3000 psi at 72 °F
  • FNPT threads seal to ANSI B 1.20.1 and ASME B 16.11
  • ASTM A105 grade material meets SA105 pressure-class requirements
  • Black finish resists corrosion in demanding plumbing systems
  • Class 3000 rating supports high-pressure pipe connections

Industrial Coupling for 2 in Pipe

This ZORO SELECT coupling is a black forged steel pipe fitting rated Class 3000. It suits industrial piping systems that require a female NPT connection on a two inch pipe size. The component meets ANSI B1.20.1, ASME B16.11 and SA105, ASTM A105 standards for pressure service.

Verify Pipe Size and Thread Standard

Confirm the existing pipe uses a two inch nominal size and female NPT threads matching ANSI B1.20.1. Ensure the system design pressure does not exceed 3000 psi at 72 degrees Fahrenheit. The fitting is restricted from sale in certain states so check local regulations before ordering.

Forged Steel Construction and FNPT Threads

The forged steel body provides mechanical strength for high pressure service up to 3000 psi. Female NPT threads allow direct assembly to male threaded pipe without additional adapters. The black finish indicates standard mill coating for carbon steel fittings.

Questions about this item

What comes in the box and do I need to buy pipe sealant or thread tape separately?

The box contains the black forged steel coupling only; pipe sealant or PTFE thread tape for the FNPT threads must be purchased separately.

How do I decide between the Class 3000 rating and a lower class for a 2 in FNPT connection?

Choose Class 3000 when the system operates up to 3000 psi at 72 °F; a lower class would not meet that pressure requirement.

What does the 3000 psi @ 72 °F rating mean once the coupling is installed in a real piping system?

It means the coupling can safely handle 3000 psi at 72 °F per ASME B16.11 and ASTM A105; pressure capacity decreases at higher temperatures.
