CNG Fuel System Inspection Labels

CNG cylinder inspection labels are applied to CNG cylinders to demonstrate the “Pass” or “Fail” result of a detailed CNG cylinder inspection. These inspections are required by the National Highway Transportation Safety Administration’s (NHTSA) FMVSS 304 which states that a detailed visual inspection of all CNG cylinders must be conducted by qualified CNG fuel system inspectors every three years or 36,000 miles (whichever comes first) and after any fire or accident.

During the inspection process, CNG fuel system inspectors must apply the appropriate inspection label to the CNG cylinder:

  • a blue “Passed CNG Cylinder Inspection” label is used when a cylinder exhibits Level 1 or no damage, and pass inspection
  • a “Failed CNG Cylinder Inspection” label is used when a cylinder exhibits Level 2 or 3 damage, or the manufacturer’s label is missing or obliterated such that positive identification is not possible

You may order CNG Cylinder Inspection labels directly from our website for $2.50 per label. Labels are sold in packs of 20.
