Anvil 361334303 hex bushing for pipe reduction

This Anvil hex bushing connects a 2-1/2 inch male NPT pipe to a 1-1/2 inch female NPT pipe. It is made from galvanized steel and rated for Class 6000 service with Schedule XXH pipe. The fitting suits industrial plumbing systems that require a durable, straight-threaded reduction.

Class 6000 rating defines pressure

The Class 6000 designation restricts use to piping built to Schedule XXH wall thickness. It is not intended for lighter schedules or lower-pressure installations. Installers must verify that the connected piping meets the same class and schedule to maintain system integrity.

2-1/2 inch MNPT to 1-1/2 inch FNPT step-down size

This specific male-to-female thread combination determines whether the bushing matches the two pipe ends being joined. It will not fit connections that require female-to-male orientation, different nominal diameters, or alternative thread standards.

Questions about this item

What does the 2-1/2" x 1-1/2" sizing mean for selecting this hex bushing?

The 2-1/2 inch male NPT end threads into a larger female fitting, while the 1-1/2 inch female NPT end accepts a smaller male pipe, reducing the connection size in one step.

What does Class 6000 tell me about how this bushing performs once installed?

Class 6000 designates the pressure rating for this forged steel fitting, meaning it is built to withstand the high pressures found in Schedule XXH piping systems.

How do the MNPT and FNPT threads affect what I can connect to this coupling?

The male NPT threads on the 2-1/2 inch side seal into a female port, while the female NPT threads on the 1-1/2 inch side receive a male pipe or nipple, giving a straight reduction with tapered threads on both ends.
