Drop by drop, gallon by gallon, hydraulic oil leakage can get expensive. What you lose goes beyond just the oil and replacement oil itself… consider energy loss, environmental issues, safety hazards, hazardous waste disposal, downtime, as well as potential legal issues. All may result in lost revenue from what could have been prevented.
Common Leak Causes
Improper Installation – wrong fitting connections
- The most common fitting (37° flare) is subjected to improper torque during assembly
- Flareless bite type fittings – imporper presetting of the ferrule on the tube
- O-ring face seal – O-ring pinched or not seated in groove, or missing completely
System Design
- Incorrect routing, bending or clamping
Poor Quality Components
- Avoid them altogether – if you can’t identify the manufacturer, don’t use it
Poor Maintenance Practices
The Parker Tube Fittings division has created a calculator to determine estimated costs associated with leakage. Run the numbers and potential loss for your operation factoring in things such as drops per minute, time of operation, cost of oil and more.
