In Puerto Rico, hydraulic oil 68 is an essential standard for industrial machinery that operates under continuous pressure, with prolonged work cycles and at high temperatures. It is not a “special” lubricant, but rather the grade that most equipment needs when the system requires a fluid with greater consistency to protect hydraulic pumps, controls, and essential components.
At American Petroleum, we offer high-performance AW 68 (anti-wear hydraulic fluid) options, designed for greater thermal stability and protection in sectors such as construction, industry, agriculture, among others.
What is hydraulic oil 68?
Simply put, 68 hydraulic oil is an oil formulated to transmit force within a hydraulic system, lubricate its internal parts, and help prevent premature wear. Although the name can be somewhat confusing, there are several important terms that are important to understand.
The 68 in its name comes from the ISO VG 68 standard, which defines how thick the oil is when measured at 40°C (104°F).
ISO 68 and VG 68 (viscosity grade 68) mean the same thing and are used to refer to that degree of viscosity, while AW 68 (anti-wear 68) is the same oil with viscosity 68, but with anti-wear additives added to protect pumps and other components when operating under high pressure and high temperatures.
What is ISO 68 hydraulic oil used for?
This type of oil, or “hydraulic fluid,” is used when equipment needs strong protection. It is common in:
- Hydraulic systems in excavators, man-lifts, loaders, cranes, forklifts, and trucks with PTO systems.
- Factory equipment such as compression equipment or industrial presses, injection machines, and automated production lines.
- Mining and agricultural machinery such as tractors, balers, harvesters, and compact loaders.
- Marine equipment and mobile machinery near the coast, where the oil must withstand high temperatures, vibrations, and humidity without failing.
Key properties of hydraulic oil 68
Hydraulic oil 68 is an industrial grade widely used in Puerto Rico for its stability in heat, humidity, and long work cycles. Among its main properties are:
Viscosity of hydraulic oil 68
Measured at 40 °C, it has a medium-high viscosity, ideal for equipment that operates for many hours without interruption.
Density of hydraulic oil 68
It is used to estimate consumption in systems measured in gallons and to ensure stable flow in pumps and hoses.
Hydraulic oil 68 temperature range
It works well when the system fluid operates between 20°C and 80°C. For prolonged heat or stored equipment that starts up with force, a 68 with good water separation and high stability is recommended for greater protection.
Types of hydraulic oil 68
68 hydraulic oils are not all the same, even if they share the same “base thickness.” The difference lies in the formula and the protection they offer depending on the equipment’s operation. Here I explain the main types in a direct and easy-to-understand way:
- AW 68 (Anti-Wear). This is the most widely used in the industry. It includes additives to protect pumps and components in equipment that works under constant pressure and heat.
- HLP 68 (DIN/ISO standard fluid). This is a mineral-based hydraulic oil that complies with industry standards such as DIN 51524-2 and ISO HM 68, offering standard protection against wear in industrial hydraulic systems.
- Premium AW 68 extended-life. This is a 68 hydraulic oil with an optimized formula to better resist heat and oxidation, allowing for less frequent changes and greater protection in equipment that works long hours under constant pressure.
- Mineral base vs. synthetic AW 68. Although both are grade 68, their performance varies depending on their base:
- Mineral base (mineral base hydraulic oil 68). A more economical option, widely used in industrial equipment and machinery in regular use.
- Synthetic base (synthetic base hydraulic oil 68). Better resistance to prolonged heat and greater stability against oxidation, recommended for equipment subjected to frequent high temperatures or more demanding conditions.
ISO 68 hydraulic oil specifications
ISO 68 hydraulic oil is classified among the most commonly used industrial grades in systems that operate under heat, pressure, and long operating cycles. Its specifications are defined by properties that ensure good performance, system protection, and fluid stability under demanding conditions.
- ISO VG classification. ISO 68 hydraulic oil is classified among the most commonly used industrial grades in systems that operate under heat, pressure, and long operating cycles. Its specifications are defined by properties that ensure good performance, system protection, and fluid stability under demanding conditions.
- Anti-wear performance (AW). AW 68 oils are reinforced with additives that help protect pumps, valves, and internal components in equipment operating under constant pressure.
- Oxidation stability. This property allows the oil to better withstand prolonged heat without losing quality quickly, which helps to space out changes depending on use.
- Demulsibility. Helps the oil separate moisture or water that enters the system, which is critical in humid climates such as Puerto Rico, to prevent components from being affected.
- Anti-foam properties. Reduces foam formation within the system, which keeps fluid pressure more stable and prevents pumping failures.
- Filtration compatibility. Works correctly with industrial filtration systems, ensuring that the oil flows without obstructions or adverse reactions when passing through the filters.
