Copper Flush Bushing 1-1/2" x 1-1/4

This wrot copper flush bushing connects a 1-1/2 inch FTG fitting to a 1-1/4 inch copper sweat fitting. It handles air, gases and potable water in residential and commercial plumbing systems. The fitting withstands a maximum operating pressure of 408 psi at 100 degrees F and a maximum temperature of 400 degrees F.

Suitable Applications and Limits

Plumbers and contractors use this bushing to reduce copper tube size in sweat assemblies for water, air or gas lines. It is not intended for threaded, press-fit or push-to-connect systems. Buyers needing a different reduction ratio, a threaded adapter or a fitting rated above 408 psi should select another component.

Critical Specification: Pressure

The decisive figure is the 408 psi maximum operating pressure at 100 degrees F combined with a 400 degrees F temperature limit. If the system design exceeds either value, this bushing is not the correct part. Verify the service conditions against these ratings before installation.
