Product Identity

The Anvil 0310090808 is a malleable iron reducing coupling rated for Class 150 service. It connects a 3 in NPT female thread to a 2 1/2 in NPT female thread in plumbing systems.

Build Integration

The coupling joins two different pipe sizes using standard NPT threads and suits Schedule 40 pipe. It handles up to 300 psi at 150 Degrees F, so the surrounding piping and seals must meet the same pressure class.

Upgrade Context

This fitting replaces a straight coupling or bushing when a pipe diameter change is required. The step-down is worthwhile when the design calls for a direct 3 in to 2 1/2 in transition without additional adapters.

Questions about this item

What is the maximum operating pressure this Class 150 reducing coupling can handle?

It is rated for 300 psi at 150 degrees Fahrenheit, suitable for Schedule 40 piping systems.

How much heat can the malleable iron body withstand during continuous operation?

The coupling is rated for a maximum operating temperature of 150 degrees Fahrenheit at its full pressure rating.

Which pipe threads must my existing piping have to connect this 3 inch to 2-1/2 inch reducer?

Both ends use female NPT threads, so your pipes need matching male NPT threads in those sizes.
