Gates/Allstar powergrip clamp shrink amount

[Junbug]

I'm planning to purchase the Gates or Allstar Performance Power grip clamps for my cooling system. What I cant deterimine is how much they shrink, so I know what size to get. I have three size hoses: 2", 1", and 5/8'-3/4". I want to get clamp sizes that will fit over the hoses but not too big where they won't shrink to fit tightly. Any one use them and have a recommendation? Is 1/16" oversize enough room for shrinkage on the smaller sizes and 1/4" oversize on the larger 2" line?
Thanks,

The grip range should be on the package.

I understand the grip range. I guess what I'm asking is the grip range what it will shrink to, or is that the range it will fit over before shrinking? I'm concerned that the flange/grip portion of the fitting that the hose slides over will be bigger than the ID of the clamp. I don't want to get a clamp thats too small or too big...

The clamp material is stiff and it's not going to fit over anything more than the large OD listed. Then will shrink to the small OD listed. Need to make sure both of your OD's fit your situation to pick the right one.

Use the smallest one that will fit.

Thanks Paul. That’s the confirmation I was looking for!
