Sanke snap rings: Y U sometimes just no snap?!

[olie]

Most of the time when I disassemble (I do ~1:10 for deep-cleaning, but sometimes for in-keg additions, too), the snap rings just pop right out and snap right back in, "as God and Mr. Sanke intended".

However, every once in a while, I get one that just won't snap back into place, and I can't quite figure out why.

Is there a trick? Some special orientation that's easier? Am I not noticing some deformity in the ring, the spear or the keg?

Any ideas, hints, pointers?

Thanks!

I don't keg, but hopefully this helps:

When I re-installing the ring on mine, it usually goes back in fine until the bend where it overlaps the first loop. While holding tension on the ring, I just take a pair of small pliers and pinch the ring into the groove and once it's started it goes fine from there. Never had an issue but my kegs are still fairly new.
