might be best explain with pics (see below)

I cannot push the tube all the way. The "o-ring" seems to be getting the way. I thought of using sandpaper (fine grit one) to reduce the tube width a bit.

But I could be doing it wrong too. Any ideas on how do it properly and safely so I don't break the tube.

I bought this style of fitting because according to what I've watched/read, I don't need to use the chamfer tool on the tube. But I do have a chamfer tool on the way. It just hasn't arrived yet.

Thank you.

Never seen that style fitting before are you sure that's for acrylic? I would think that is for copper tubes. Try a little olive oil for lube. You don't necessarily need a big camfer take some fine sand paper and lightly sand the bottom edge to get rid of burs but I think you have the wrong fittings, can you post a link for the fittings and the tube you bought.
