Steel and aluminum cylinder testing.
Testing support for eligible metal cylinders across scuba, oxygen, nitrogen, storage, and other high-pressure applications.

For owners who know the material but need application-specific help.
Steel and aluminum describe cylinder construction, but the intended service and specification markings determine how the request should be reviewed.
Include the gas service or equipment use, plus clear shoulder markings, so we can route the cylinder correctly.
Details that help us review your cylinder
- Steel or aluminum material
- Scuba, oxygen, nitrogen, or other use
- Manufacturer and specification stamps
- Last hydrostatic test marking
- Valve status, size, and quantity
What can affect acceptance and timing.
Every cylinder is considered by its own markings, construction, condition, and intended service. Sending clear information before drop-off helps avoid delays.
Material
Steel and aluminum cylinders have different physical characteristics and inspection concerns.
Intended use
The same material may appear in very different cylinder applications.
Identification
Stamped specification and manufacturer information is more useful than color alone.
Local service with advance-arranged after-hours access.
Drop off and pick up at 575 Dawson Dr, Ste 9, Camarillo, CA 93012. A 24/7 drop area is available only when arranged with us in advance.
We normally quote approximately one week. Current testing volume, cylinder condition, or additional review may extend that timeline.
