Value Brand 1MNA1 Black Forged Steel Coupling

This Value Brand 1MNA1 coupling is a pipe fitting manufactured from black forged steel to ASTM A105 and SA105 specifications. It meets ANSI B1.20.1 and ASME B16.11 standards for threaded connections. The fitting carries a Class 3000 rating with a maximum pressure of 3000 psi at 72 degrees Fahrenheit. It is sold new for general plumbing and industrial piping assemblies.

Suits installers needing a Class 3000 FNPT joint

This coupling suits installers who require a female NPT threaded joint rated for 3000 psi service at 72 degrees Fahrenheit. It is not for systems that specify a different pressure class, a different thread standard, or a socket-weld or butt-weld connection. Buyers needing a larger or smaller pipe size must select the matching fitting for their nominal bore.

1/4 inch FNPT connection with 3000 psi rating

The single specification that decides fitment is the 1/4 inch pipe size with FNPT threading. The coupling accepts male NPT threads on both ends and is rated to 3000 psi at 72 degrees Fahrenheit per ASME B16.11 Class 3000. Verify the pipe schedule and thread type against your system drawings before ordering.

Questions about this item

What comes in the box and do I need to buy thread sealant or extra fittings?

The box contains the single 1/4 in FNPT forged steel coupling. Thread sealant tape or pipe dope and any mating pipe nipples are not included and must be purchased separately.

How do I choose between the listed standards ANSI B 1.20.1, ASME B 16.11 and SA105, ASTM A105 for my installation?

All three standards apply to the same coupling; they describe thread form, forging quality and material grade together, so you do not select between them — the fitting meets each one simultaneously.

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

It indicates the maximum working pressure at 72 °F; at higher temperatures the allowable pressure drops, so the system design must stay at or below the rated limit for the actual operating temperature.
