Anvil Malleable Iron Reducer Coupling

This Anvil 0310087606 coupling joins 1-1/4 inch and 1 inch NPT female threads in malleable iron. It is built for Class 150 service and fits Schedule 40 pipe in plumbing and drain installations. The fitting suits contractors and maintenance teams needing a durable transition between two pipe sizes.

Class 150 rating with 300 psi pressure limit

Rated for 300 psi at 150 degrees F, the coupling handles typical water, air and non-corrosive fluid lines within Class 150 parameters. It is not suited for pressures above this threshold or for temperatures exceeding the stated maximum. The malleable iron body provides mechanical strength for standard drain and supply runs.

Replaces worn or mismatched thread transitions

Use this reducer to replace a damaged coupling or to step down from 1-1/4 inch to 1 inch NPT without changing the pipe schedule. The jump is worth it when the existing line is Schedule 40 and the system operates within the Class 150 pressure and temperature envelope. It does not adapt to other thread standards or pipe schedules.

Questions about this item

Will this Class 150 malleable iron reducer coupling mate with existing Schedule 40 piping that has 1-1/4 in and 1 in NPT threads?

Yes, the coupling is designed for Schedule 40 pipe and provides female NPT threads in both 1-1/4 in and 1 in sizes for direct connection.

How can I verify the joint is holding the rated 300 psi at 150 °F after installation?

Pressurise the system to its working pressure and inspect both threaded connections for leaks; a tight, dry joint confirms the Class 150 rating is being met.

Does the Anvil 0310087606 package include thread sealant or gaskets, or must they be purchased separately?

The reducer coupling is supplied as the fitting only; pipe thread sealant or tape must be obtained separately to complete the NPT connections.
