Reducing coupling for pipe connections

This Anvil 0310543608 reducing coupling joins a 1-1/4 inch female NPT pipe to a 1/2 inch female NPT pipe. It is made from malleable iron and rated for Schedule 80 piping systems. The fitting handles a maximum operating pressure of 500 psi at 150 degrees Fahrenheit. It is a Class 300 component suited for straight, threaded installations.

Installers needing a straight threaded reducer

Plumbers and maintenance technicians use this coupling to step down pipe sizes in high-pressure systems. It is not for applications requiring a different thread standard, a lower pressure class, or a material other than malleable iron. Buyers who need a drain trap assembly rather than a straight reducer should look at another product type.

Class 300 Schedule 80 pressure rating

The fitting carries a Class 300 designation and is built for Schedule 80 pipe, giving it a 500 psi maximum operating pressure at 150 degrees Fahrenheit. This pressure rating is the primary specification that determines whether the coupling matches the system requirements. Verify the system pressure and pipe schedule before ordering.

Questions about this item

Will the malleable iron construction handle continuous 500 psi pressure without excessive heat buildup?

The fitting is rated for 500 psi at 150 degrees F maximum operating pressure, and malleable iron dissipates heat effectively in static plumbing installations.

Do I need matching Schedule 80 pipe and Class 300 fittings on both the 1-1/4 inch and 1/2 inch FNPT ends?

Yes, the reducer coupling is manufactured to Schedule 80 and Class 300 specifications, so mating components should meet the same ratings for full 500 psi service.

Can I thread this Schedule 80 Class 300 reducer onto existing Schedule 80 pipe of the same nominal sizes?

The FNPT threads follow standard taper pipe thread dimensions for 1-1/4 inch and 1/2 inch nominal sizes, allowing assembly with compatible Schedule 80 pipe nipples or fittings.
