Here is some info from page 8 of the pandora thread in the gallery, posted by Amy (girlarchitect):

I use Santa Fe Jeweler's Supply http://www.sfjssantafe.com, and have been really happy with their quick service, online ordering and online pricing. I use the#18200 silver tubing with my 3/16" mandrels it has a 5.03mm OD and a 4.3mm ID. The walls are pretty thin. If you use the size smaller, it will flare and fit the bead, but won't fit over the Pandora/Biagi bracelet end, but will fit Troll. Hope that gives everyone another option.

Another Amy (Steamer) replied that the 5mm O.D. tubing she bought did not quite fit her Pandora. So, it looks like you need this slightly larger 5.03 O.D./4.3mm I.D. size.

I've been searching the LE threads for the answer to this question, too!
If anyone has more info, please share!

i have tried to double dip my 3/16 and still have not gotten them to fit on a pandora..the 1/4 mandrel fits but is a bit sloppy..i have not been able to find a mandrel in between those 2 sizes..if anybody knows where to find a size in between i'd love to know..thx

bummer, Renee Are your beads silver cored? I don't know an in-between mandrel size... it would be called a 7/32" I'm guessing and I've never heard of one.

Here is more info from LyndaJ from the "Tools to line beads w/sterling silver" thread from this forum:

Here's a summary of Rio part numbers, mandrel size, and outer diameter of tubing needed.

3/32" 100-955 OD: .114"; ID: .082"
5/32" 100-905 OD: .188"; ID: .156"
3/16" 100-905 OD: .188"; ID: .156" This should work for both 5/32 and 3/16.
1/4" 100-907/14 OD: .250"; ID: .218"
1/2" 100-907/12 OD: .500"; ID: .468"
