A floor jack that slowly creeps downward under load is a serious safety hazard. Whether you’re working on a driveway in Winter Park or a garage in Downtown Orlando, Central Florida’s high humidity and intense heat can accelerate wear on internal seals, valve O-rings, and hydraulic fluid performance.
Here is why your floor jack is losing pressure and how to address it safely.
Top Reasons Your Floor Jack Is Bleeding Pressure
Trapped Air in the Hydraulic Lines: Air bubbles inside the fluid reservoir compress under load, preventing the cylinder from holding steady pressure and causing the arm to sink.
Worn or Damaged Internal Seals: Heat and age break down rubber O-rings and piston seals. When these leak internally, hydraulic fluid slips past the piston without holding weight.
Loose or Failing Release Valve: If the release valve isn’t fully closed or the valve seat is pitted with rust or dirt, fluid leaks back into the reservoir under load.
Low or Contaminated Hydraulic Oil: Low fluid levels prevent complete pressure build, while moisture accumulation from Orlando’s high humidity contaminates fluid and degrades internal components.
Overloading the Rated Capacity: Exceeding your jack’s tonnage rating forces fluid past internal bypass valves as a safety blow-off, slowly lowering the saddle.
Immediate Safety Rules & Helpful Resources
Critical Safety Risk
Never get under a vehicle supported only by a hydraulic floor jack. Hydraulic jacks are designed for lifting, not holding weight. Always set the vehicle securely on rated jack stands before placing any body part underneath.
