This tubing is marked 6.5mm x 10mm. It actually measures a bit over 6.5mm ID. This tubing will work with true 1/4" barb connectors, but be careful. I purchased some 1/4" barbs that are actually 6mm. This oversized tubing will not even clamp down to the undersized barbs. I wish the actual size was listed on these items.
