What is the difference between ISO 32 and ISO 68?

Viscosity grades

ISO grades measure viscosity at 104°F(40°C). When you look at, for instance, ISO 32 hydraulic oil it will flow much more quickly than ISO 68 hydraulic oil. Different viscosities are better for different applications in the field.

What is the difference between 32 and 68 hydraulic oil?

32 is thinner, No. 46 is medium and No. 68 is thicker. Generally speaking, if the temperature is low in winter, use #32 & #46 hydraulic oil with a lower viscosity, and use #68 hydraulic oil with a higher viscosity in summer.

What is ISO 68 oil used for?

Hydraulic oil 68 grade is most commonly used for hydraulics with vane-, piston-, or gear-type pumps, especially where pressures exceed 1000 psi. They can also be used to lubricate lightly loaded reciprocating compressors.

What is ISO 32 used for?

ISO 32-46-68-100 Hydraulic Oil Temperature Range | Hydraulic Oil Specification Chart. What is hydraulic oil? Hydraulic oil (also known as hydraulic fluid) can be synthetic or mineral based. It's a non-compressible fluid that is used to transfer power within hydraulic machinery and equipment.

Can you mix ISO 32 and ISO 68 hydraulic oil?

Mixing oils with different additive packages is never recommended. Doing so could compromise the additive performance of both constituents, cause corrosion of component surfaces and lead to increased mechanical wear.

Hydraulic Oil Types

What happens if you put hydraulic oil in a diesel engine?

What Happens If You Put Hydraulic Fluid In A Diesel Engine? A DEF-containing oil can cause an emulsion or separation of layers within an oil reservoir if it is introduced into an engine, transmission, or hydraulic oil. In this case, the oil flow may be inefficient, or the oil pump or system components may be damaged.

What ISO is universal hydraulic oil?

Cross reference Universal Tractor Hydraulic Fluid

The ISO grade (32, 46, 68) fluid to be used should fall within the range of the optimum cSt listed in the right-hand column of the spec sheet.

What is ISO grade 68 oil?

Hydraulic 68 is part of Crown Oil's range of premium-grade mineral-based hydraulic oils with good anti-wear properties providing protection in the most demanding of systems while still meeting ISO standards for hydraulic oil. This hydraulic fluid is rust, corrosion and oxidation inhibited.

What is ISO 68 oil equivalent?

Obviously, SAE and ISO use two different scales to measure viscosity. SAE 10W is equivalent to ISO 32, SAE 20 is equivalent to ISO 46 and 68, and SAE 30 is equivalent to ISO 100.

What is ISO 32 oil?

Hydraulic 32 is part of Crown Oil's range of premium-grade mineral-based hydraulic oils with good anti-wear properties providing protection in the most demanding of systems while still meeting ISO standards for hydraulic oil. This hydraulic fluid is rust, corrosion and oxidation inhibited.

What does AW 32 mean in hydraulic oil?

For example, AW 46 hydraulic oil is used to operate the hydraulic systems in off road equipment such as dump trucks, excavators, and backhoes, while AW 32 hydraulic oil colder weather application, like in a snow plow's pump.

What is AW ISO 32 hydraulic oil used for?

ISO 32, 46 and 68 grades are most commonly used for hydraulics with vane-, piston-, or gear-type pumps, especially where pressures exceed 1000 psi. They can also be used to lubricate lightly loaded reciprocating compressors.

What happens if you use the wrong hydraulic fluid?

Whether it is changing hydraulic filters too often or using the wrong type of hydraulic fluid, these errors can lead to serious problems such as unnecessary maintenance costs, increased repair costs, system downtime, premature wear of components, and even catastrophic failure.

What hydraulic oil is best for cold weather?

Minus 70 Hydraulic Oil is a special anti-wear hydraulic oil designed for extreme low temperature operations where high fluid mobility is of utmost importance. This oil has an extremely high viscosity index which guarantees excellent fluidity and very low torque under these adverse cold conditions.

What viscosity is ISO 32?

For example, ISO viscosity grade 32 relates to the viscosity bracket 28.8 to 35.2 mm2/s, the mid point of which is 32.0 mm2/s.

What does ISO VG 32 mean?

NYBASE ISO VG 32 is a mid-range viscosity speciality base oil for Group I replacement, with high Viscosity Index (VI), excellent low temperature and solvency properties. Recommended for the formulation of industrial, automotive and metal working fluids.

Is ISO 68 mineral oil?

ISO Grade 68, Mineral oil. Designed to perform in the most demanding hydraulic systems and air compressors.

What is AW 68 hydraulic oil used for?

ISO 32, 46 and 68 grades are most commonly used for hydraulics with vane-, piston-, or gear-type pumps, especially where pressures exceed 1000 psi. They can also be used to lubricate lightly loaded reciprocating compressors.

What viscosity is AW 32 hydraulic oil?

AW 32 hydraulic fluids have an International Standards Viscosity Grade or ISO VG of 32. This is the thickness of the fluid tested at 40 degrees Celsius. ISO VG 32 has good cold weather flow capabilities and its thickness is equivalent to a SAE 10 weight lubricant.

What oil is thicker AW32 or AW46?

AW means Anti-Wear. The lower the number, the thinner the oil and the more easily it flows. AW-32 is neither "better nor worse" than AW-46. The numbers refer only to the viscosity, not to the quality.

Can you burn hydraulic fluid in a diesel truck?

Can Hydraulic Oil Be Used As Diesel Fuel? Researchers at the Diesel Fuels Research Institute have found that Hydraulic oil can be used in most diesel engines year-round. If it were really cold, you could blend it with D1 at 50% or gasoline at about 5%, depending on the weather.
