Size of stepless or oetiker clamp for 1/4" gas line

Is 13/32" the right size of stepless clamp for 1/4" gas line? I've included a link to the product I'm thinking of ordering.

Well I was searching the forum hoping to find an answer to this question myself...too bad you never got an answer in over 2 years. If no-one knows I'll be giving AHS a call this week to confirm as this is the only size Oetiker listed on the site. Here's the updated link:

"This is an inexpensive solution for holding beer line and air line on tees, nipples, and disconnects"

Posted size is 1/2", none of their 'air line' or 'beer line' hoses are 1/2" OD, can anyone confirm if this is a one-size-fits-all when it comes to clamping keg lines for beer and gas? Or if any of their clamps listed are specifically for beer or gas lines? http://www.austinhomebrew.com/Beer/Clamps/

Go here, and it may help you with sizing before you order.
