What dose this mean? Filter tube

I have a Tetra Ex700 (canister filter), I just purchased a spare canister tube which has it specs. Was wondering what 11.3mm? Is it inner or outer diameter?

If you know the specs because I want to buy a cheaper brand.

I'm not quite sure what you are asking - you have a canister filter, and you have the tubing, but you still want to know the diameter? You can check with a ruler or a set of calipers...

I believe the 11.3 mm measurement refers to the inner diameter. The outer diameter is probably closer to 16 mm.

Re: What dose this mean? Filter tube

You have put me to shame, spent an hour looking for the specs and haven't thought of using a ruler. :banghead: My laziness has made it a habit to check online instead of using a practical method. Cant read an exact but estimate is11.3mm for the inner diameter and 16mm for the outer diameter.

I'm not into the image, but into the hobby...
