DOT Cylinder Repair &
Recertification

Return your Out-of-Date DOT Cylinders back to Optimum Service

Often smaller than permanently installed ASME tanks, DOT propane cylinders meet the Department of Transportation’s requirements for portability of propane within a cylinder. Because certain risk comes with relocating or moving a propane-filled tank, maintenance is key and requires recertification of these cylinders 12 years after original manufacture and every five years for the life of the DOT cylinder.

Cylinder maintenance does not have to be a chore. At LP Cylinder Service, we alleviate your concerns with staying DOT compliant by providing round-trip transportation and industry leading quality and service for your propane equipment assets. Your portable propane cylinders undergo an eight-point process for complete repair and recertification.
