Kitchen recently remodeled. Cabinet installer ran 20-feet of soft
copper tubing from sink to refrigerator. Not enough slack behind
refrigerator. I don't like the path of the tubing. It could be pinched
or broken.

I should have had a new copper-pipe supply line run from the kitchen
sink to the refrigerator. Now, it would be very difficult to sweat a
rigid line in the back of the new cabinets.

The McMaster-Carr catalog lists red brass threaded pipe (schedule 40,
WWN-351a, ASTM B43-91) and red brass threaded fittings.

Is red-brass threaded pipe appropriate for a rigid line from the
kitchen sink to the wall behind the refrigerator?

Thanks,

Joel Zink
