I'll see what I can answer.
Is the flat washer inside the collar just a spare?
I believe it's a spare. They don't attach as well as the O-ring does, so the flat washer falls off easily and can roll somewhere where you lose it, so I think it was included for this reason.
The other question on the lock collar - there appears to be a degree of play between the collar and the tubing (just putting them together - no glue). I'm using Monsoon hardline tubing. Is this the same experience others have had?
Yes, it's loose and not tight. If you try other tubing like the Primochill tubing, the lock collar will fit on very tightly, but then you run into the issue of the tubing cracking due to the stress.
It seems like it would be easy to accidentally glue the collar and tube with a minute offset, an offset that would be enough to cause either an immediate leak, a slow leak or an eventual catastrophic failure of the fitting, like I have seen in this thread.
Yes, that's exactly what happened to me. What I did was I applied glue and slipped it onto the tubing, then spun it around to see if any gaps appear in the glue. Chances are you have to do this a few times until it completely fills up. It'll feel like you're putting on a ton of glue, way over how much it feels like you need, but it's required to fill in the large gap between the tubing and the collar.
G1/4 fitting - I see there are two sets of round washers included, I assume I pick a colour and use just one on the G1/4 end?
Yep, just use one O-ring of whichever color you want.
Some other advice: use the included tool (spade side) to tighten down the G1/4 fitting, but don't use the other side of the tool (the prong side) to tighten down the locking 'receptacle' (the leftmost white thing in your picture). Just finger tighten it. This is because you should be able to get it more than tight enough with just your fingers, and the tool slips too easily, which can scratch your tubing. It will also strip the paint off the white locking receptacle and make it look uglier.
If you're looking for an alternative glue that doesn't become malleable with heat, you can look into getting some acrylic glue, the kind that actually bonds the acrylic together by melting it rather than simply gluing it together. Also look out for your lock collars cracking. You'll probably want to check every few days, especially after long gaming marathons, as the large temperature changes will stress the lock collars and glue.
Another option is to look at the Monsoon economy hardline fittings, which is a simple compression fitting like the Primochill fittings, instead of using lock collars.Edited by Ranma13 - 1/13/15 at 2:17am
