Questions about this item

What does the Schedule 40 rating mean when this coupling is installed?

Schedule 40 indicates the wall-thickness standard for the pipe this coupling joins, so it matches standard-pressure brass piping systems.

How does the compression interface seal on 1 1/4 in female pipe?

The compression nuts and ferrules tighten onto the pipe outer diameter, creating a metal-to-metal seal without solder or threads.

What clearance is needed to fit the 1 1/2 in compression nut during installation?

Allow enough space for a wrench to turn the 1 1/2 in compression nut and for the ferrule to seat fully on the pipe end.
