(Apologies in advance folks - I'm new to compression fit connections so I suspect this is an obvious question).
I'm preparing to reconnect an old copper tube to my water supply line and refrigerator for the ice maker. Here's what I see at the end that's near my sink:
The key point that concerns me is that there's no compression nut at all and the compression ring/olive is on there pretty good. I'm not sure how this could have happened but oh well.
My current plan of attack is:
1) Cut off the old compression ring section.
2) Lightly clean the end to ensure there isn't any dirt and debris.
3) Place the compression NUT on first (which seems to come with most water supply valves of appropriate size.
4) Please the compression RING on second.
5) Place the tube in the compression seat of the shutoff valve.
6) Tighten the nut.
Is it really that simple or am I missing something?
I'm confused on a few things:
What actually tightens the ring seal to the tubing? Is that done when I'm tightening the nut? Or do I need to apply some sort of glue around the base?
Do I need to wrap anything in plumbers tape?
How far up the tubing should the ring/olive be? In the old piece, it looks like it was placed about 3/8" to 1/4" up but I'm not sure if that's recommended or not.
