Default boil kettle dip tube questions

I'm building a dip tube for my keggle. I'm planning on soldering some copper together, and then holding it into the coupler with a compression fitting. I hear everyone talk about replacing the metal collar in the compression fitting with an o ring or two. Do these need to be silicone o-rings like the weldless bulkhead uses? I'm guessing they do huh? Also, I boil with whole hops. Should I plan on needing a hop sack, or will a ss scrubby work well enough to filter whole hops? I'll be gravity draining through a CFC..

Thanks for any feedback!

If you're using whole hops, there's no need for a hop bag. They won't clog anything. Here's a picture of my dip tube. It works great and sucks all but about 1 cup out of the keggle. I just put a strainer on top of my fermentor to keep all the sludge out.

It will seal without permanently crimping the tube.

Why would crimping the tube be a problem?

BTW, my comp fitting seals and I can still take it all apart. It doesn't need to be crimped completely to seal.

I hear it recommended by a lot of people, many of which seem to have a lot experience building keggles or systems. Like Bobby_M. Anyone have pictures of scrubbies under there dip tubes that act as filters? I can't imagine that hop sludge isn't going to get sucked through the system. Hate to have that clog the CFC..

OK, but are they reccommending it just to sell you o-rings or is there an actual reason for doing it?

So that it can be taken apart and cleaned easily as needed.

You don't need the Orings to do that.
