Forged Steel Hex Bushing Class 6000

This forged steel hex bushing connects a 2 inch male NPT thread to a 1 1/4 inch female NPT thread. It is built for high-pressure piping systems that require a Class 6000 rating. The fitting meets ASTM A105, ASME B 16.11 and ANSI/ASME B 1.20.1 standards. It suits installers who need a durable, code-compliant reducer for demanding service conditions.

Temperature and pressure limits

The fitting operates from -20 degrees to 150 degrees Fahrenheit. Class 6000 defines the pressure envelope for the forged steel body at these temperatures. Designers must verify that system pressure and temperature stay within this envelope. Exceeding either limit voids the rating and risks joint failure.

Sizing headroom and installation

The 2 inch by 1 1/4 inch step-down covers a common reduction in heavy-duty pipework. A 2 33/64 inch hex provides a positive wrench grip for assembly torque. Systems needing a larger reduction or a different thread standard cannot use this bushing. It is not for low-pressure schedules or non-NPT thread forms.

Questions about this item

Should I choose the 2 in x 1 1/4 in hex bushing or a different size for my piping?

Select the 2 in x 1 1/4 in hex bushing when you need to reduce a 2-inch male NPT thread down to a 1 1/4-inch female NPT thread; match the exact pipe sizes in your system.

What does the Class 6000 rating mean once the bushing is installed?

Class 6000 indicates the forged steel fitting is designed for high-pressure service up to 6000 psi at the rated temperature range of -20 to 150 degrees F.

How do the MNPT x FNPT threads and ASME B16.11 standard limit what I can connect?

The MNPT x FNPT connection follows ANSI/ASME B1.20.1 taper threads, while ASME B16.11 governs the forged dimensions and pressure class, so only matching NPT threads in Class 6000 service should be used.
