Reducer Coupling for Schedule 40 Pipe

This Anvil malleable iron reducer coupling joins one-inch and three-quarter-inch female NPT threads on Schedule 40 piping. It is rated for Class 150 service and suits plumbing or hydronic systems that require a step-down connection. Installers use it where a straight coupling cannot match the pipe sizes.

Class 150 Rating and 300 psi Limit

The fitting handles up to 300 psi at 150 degrees Fahrenheit, giving headroom for typical residential and light-commercial water or steam lines. Pressure spikes above the rating or temperatures beyond the stated maximum will exceed the design envelope. It is not intended for high-pressure process piping or extreme temperature cycles.

Malleable Iron Construction and NPT Threads

Malleable iron provides mechanical strength and impact resistance for threaded joints that may see vibration or thermal movement. Female NPT threads on both ends allow direct assembly without adapters, reducing potential leak paths. The material is not suited for highly corrosive fluids without additional protection.

Questions about this item

Will the 1 in NPT end of this Class 150 malleable iron reducer coupling thread onto my existing Schedule 40 pipe?

Yes, the 1 in female NPT end is made for Schedule 40 pipe, and the Class 150 rating supports 300 psi at 150 °F.

How can I confirm the reducer coupling is seated and leak-free after installation?

Pressurise the line up to the 300 psi rating and check the 1 in and 3/4 in NPT joints for any weeping.

Does the box include pipe sealant or do I need to buy thread tape separately?

The coupling is supplied alone; you must provide your own thread sealant or tape for the NPT connections.
