Hydraulic fluids are formulated for specific machinery; using them in general plumbing may not provide the necessary lubrication or sealing properties. Consult a specialist for appropriate leak solutions.

Carefully follow the manufacturer’s instructions for application, usually involving controlled dosing into the drain line followed by flushing with water. Avoid prolonged exposure to high concentrations of cleaning agents.
