CGS performs hydrostatic testing and visual inspections per DOT regulations, CGA requirements and PSI/PCI standards. Every cylinder is returned with a nominal charge of certified breathing air to ensure zero contamination and a visual inspection label that conforms to industry standards.

Our trained technicians can clean and label your cylinder for oxygen-enriched service for a low, fixed rate.

Annual inspections are only $5 and can be performed while you wait.


We know that Self Contained Breathing Apparatus (SCBA) cylinders can take a beating. We can perform DOT approved repairs and hydro test fiber-wrapped SCBA cylinders at a fraction of the price of our competitors.

Paint Ball

Hydro testing your paintball cylinder doesn’t need to be headache. With low, fixed-pricing and quick turn times, there is no reason to send your cylinders anywhere else!


Our staff is well-versed on the requirements of cylinders in oxygen service. We have the capability to quickly hydrostatically test, purge, and leak-check your oxygen cylinders for a low fixed-price. Every hydro test includes a new neck seal and external valve cleaning to ensure your safety and trouble-free operation.

We have a dedicated oxygen clean-room where we can safely overhaul and repair the most common oxygen valves in service today, along with the capability to clean contaminated cylinders and regulators.
