Cylinder Testing

C and R Testing can help you with both visual and hydro cylinder testing. We also oxygen clean cylinders and service cylinder valves.

The time needed between tests and type of test (visual and hydrostatic) depends upon what you use the cylinder for.  
Diving cylinders require testing every 2.5 years (visual every 2.5 years and a hydrostatic every 5 years): 
For example a cylinder manufactured in 10/2002: 

  • requires a visual test - 04/2005
  • requires a hydrostatic test - 10/2007

A cylinder not used for diving (air rifle, storage vessels etc)  only require a hydrostatic test every 5 years 

Cylinders that require O2 cleaning have to be re-cleaned every 15 months.
