Here is a pic, the 2x2 1/2x4"L all black is in the left bottom corner, the others with the orange can be seen next to it. In the pic the orange lined ones are 3" long, the one you will get will be 4" long. The solid black seems tighter wound in the reinforcement, but the ones with orange linner are thicker????
up to 30 psi should be no problem with either one.
