Hydrostatic Pressure Testing
Please Note: when sending in an Oxygen Bottle for a Hydrostatic Test, we require you to also send the page from the CMM with the approved data relating to the oxygen bottle service.
The test station can perform DOT Hydrostatic testing of your portable aviation Oxygen, Fire and Inflation cylinders.
We test all brands’ portable Aviation Gas Cylinders. We offer Hydrostatic testing of onboard aircraft O2 cylinders. Have your mechanic remove and ship us your bottle.
Our hydrostatic test station with precision “Crystal Engineering” Pressure test gauges can apply pressure over 10,000 psi.
We know aluminium, steel, and composite aviation cylinders. We have the proper equipment to inspect, test, and clean oxygen cylinders.
Our test station labels apply to the cylinders and will not damage the composite lining.
We can also perform all basic repairs to damage such as dents, scratches, cuts, rust, corrosion, and re-painting when required.
Oxygen Regulator – Timex
Please consider the following to speed up turnaround time, especially in “AOG” Aircraft on Ground scenarios, regarding Timex on oxygen bottles.
When you anticipate the scheduled maintenance event, known as the Timex, for the oxygen bottle on the aircraft.
We strongly recommend reading the “CMM” Component Maintenance Manual and determining if the oxygen regulator needs an overhaul.
If so, please contact the “OEM” Original Equipment Manufacturer and obtain a new oxygen regulator.
Then, send in the new oxygen regulator and the oxygen bottle for its five-year hydrostatic test.
Upon completion and release, we will return the expired oxygen regulator and the oxygen bottle fitted with the new regulator.
Regarding the old oxygen regulator, please send it to the “OEM” for an exchange part overhaul, then keep that as your part for the next five-year hydrostatic pressure tests.

Oxygen Bottles
DOT Class Cylinders
Department of Transportation (DOT) requires that all aircraft oxygen cylinders be hydrostatically tested regularly to verify that they can operate under high-pressure circumstances and are free of stress fractures and rust.
Different types of oxygen cylinders require varying testing durations and service life criteria:
- 3AA oxygen cylinders: Test once every five years with indefinite service life.
- 3HT oxygen cylinders: Must test every three years with a 24-year service life.
- Composite oxygen cylinders: Implement testing every five years with a 15-year service life.
To verify that your cylinders are not out of their scheduled hydrostatic due dates, look for the test dates stamped or labeled on the cylinders.
Imported New Aviation Cylinders
It should be noted that by the Gas Cylinder Test Scheme and AS2337 & AS2030.
Before getting re-gassed, any older cylinders must be checked to see if the Gas Cylinder Test Stamp is current.

Failing to do so leaves the operator and the re-filler at risk of injury and prosecution if someone is injured.
