We've Rebranded!
Cylinder Training Services International is now CYLINDEX! Though our site and online shop have a new coat of paint, we remain committed to educating and innovating in the high-pressure cylinder space. For questions or concerns, check out our FAQ Page.
ATTENTION VISUAL INSPECTORS! We will be hosting two C.A.T. courses at the annual Dive Equipment and Marketing Association (DEMA) Convention in Orlando on November 10, 2025. We are offering discounted rates for those looking to renew, crossover, or earn their visual inspection certification. View the Cylinder Assessment Technician course for more information.
