Using non-vex sold latex tubing

Hello guys. My team and I are making a catapult, but we are having snapping issues with our rubber bands. We’ve recently seemed teams use latex tubing, but with competition coming up, we are not sure if the latex tubing would come on time if we bought directly from VEX. We’ve found latex tubing sold from amazon, with the exact same dimensions, but are questioning the legality.

Do any of you guys know if we can use non-vex latex tubing?
