Anvil Hex Bushing Class 125

This Anvil hex bushing is a malleable iron pipe fitting rated for Class 125 service. It connects a 2 1/2 inch male NPT thread to a 1/2 inch female NPT thread. The fitting handles a maximum operating pressure of 175 psi at 150 degrees Fahrenheit. It is designed for use with Schedule 40 pipe in plumbing and piping installations.

Suits standard NPT reductions.

This bushing suits installers reducing a 2 1/2 inch male NPT line to a 1/2 inch female NPT port within Class 125 pressure limits. It is not for systems that require a higher pressure class than Class 125. It is also not for applications that demand a different thread standard or a female thread size other than 1/2 inch NPT. Buyers needing a different pressure rating or thread combination must select another fitting.

Class 125 pressure rating decides fit

The single specification that decides whether this is the right part is the Class 125 pressure rating combined with the 175 psi at 150 degrees Fahrenheit maximum operating pressure. If the piping system operates above this pressure or temperature limit, this bushing is not suitable. Verify the system design pressure and temperature against this rating before purchase.

Questions about this item

Will the cast-iron threads on the 2-1/2 in male NPT end need periodic re-sealing?

The bushing is cast iron with NPT threads; apply fresh pipe-thread sealant each time the joint is broken and re-made.

What pressure limit governs continuous service on a Schedule 40 system?

The fitting is rated 175 psi at 150 °F, which is the maximum operating pressure for sustained use.

Does the malleable iron body run hot or transmit vibration when water flows all day?

Cast iron absorbs vibration and runs at fluid temperature; no active cooling or noise concerns exist.
