HYDRAULIC OIL (PETROLEUM) & PVDF Compatibility

Hydraulic Oil (Petroleum) is a mineral-oil based fluid with anti-wear, anti-foam and oxidation-inhibiting additives. It has a specific gravity of about 0.86 to 0.88 and a high flash point, often above 400°F (204°C). It transmits power in hydraulic presses, injection molding machines, mobile equipment and lifts. Bulk hydraulic oil and used oil tanks need secondary containment and protection from water and dirt. Use the compatibility ratings to choose the right tank resin, fittings and gaskets.
