Questions about this item

What copper tubing size does the 1" CTS ring compression nut assembly connect to?

The 1" CTS designation means the nut assembly is sized for 1" copper tube size tubing, which has a 1-1/8" outside diameter.

Can the bronze nut assembly be used with existing copper pipe that has minor surface corrosion?

The compression ring can seal against clean, round copper pipe; heavy corrosion or deep pitting should be removed or the pipe replaced before installation.

After tightening the nut, how can I confirm the joint is watertight?

Pressurise the system and inspect the joint; a properly made compression seal will show no drips or moisture at the fitting.
