Value Brand 1MNC9 Black Forged Steel Union Class 3000

SKU CH-G11T-6P0X4

Black forged steel pipe union with FNPT connections rated to 3000 psi at 72 degrees F

  • Rated for 3000 psi working pressure at 72 Degrees F
  • Threaded FNPT connection matches ANSI B 1.20. 1 pipe standards
  • Black forged steel body built to ASME B 16.11 and SA105 specs
  • ASTM A105 material grade ensures high-temperature strength
  • Union design allows quick pipe disassembly without cutting

1/2" Black Forged Steel Union

This 1/2 inch union joins two pipe sections with female NPT threads. It is made from black forged steel rated to Class 3000 for high-pressure systems. The fitting suits installers who need a removable joint that can be disassembled without cutting pipe. It is not for buyers who want a permanent welded connection or a compression-style fitting.

Threaded Connection and Standards

The FNPT threads meet ANSI B1.20.1 and ASME B16.11 dimensional requirements. The body material conforms to ASTM A105 and SA105 specifications for forged carbon steel. These standards ensure compatibility with matching threaded pipe and fittings in the same class. The union requires no special tools beyond standard pipe wrenches for assembly.

Class 3000 Pressure Rating

The union withstands 3000 psi at 72 degrees Fahrenheit, providing headroom for demanding hydraulic or steam lines. Pressure capacity decreases as temperature rises above the rated point, so designers must verify derating curves for their specific service conditions. It is not suited for applications exceeding the Class 3000 limit or for cryogenic temperatures where material embrittlement may occur.

Questions about this item

What is the maximum working pressure this Class 3000 forged steel union can handle?

The union is rated for a maximum pressure of 3000 psi at 72 degrees Fahrenheit.

How much heat can the union tolerate before its pressure rating is affected?

The 3000 psi rating applies at 72 degrees Fahrenheit; pressure capacity decreases as temperature rises above that level.

Which pipe thread standard must the mating pipes follow for a proper seal?

The FNPT connections conform to ANSI B1.20.1, so the connecting pipes must use matching National Pipe Taper threads.
