A tube plug seal has an improved tear line pattern which tears when a mating tube having a circumference smaller than the seal is inserted through the seal. The improved tear line pattern is designed to initially tear where the circumference of the mating tube applies the highest stress. As a result, the improved tear line includes a portion which extends at least partially circumferentially about an axial center point of the seal. More specifically, the circumferential portion of the improved tear line pattern generally aligns with a circumference of the mating tube. In one embodiment the improved tear line pattern is C-shaped.
