BUYER'S GUIDE

How to Choose an Industrial Lubricant, Oil, or Grease

Choosing the right lubricant starts with understanding your application, operating environment, and the chemicals or loads your components will encounter.

  • Hydraulic oil transfers power, lubricates moving parts, and protects pumps, valves, and cylinders inside hydraulic systems. The right viscosity grade and additive package help maintain consistent performance, control wear, and resist oxidation across a range of operating temperatures and pressures.
  • Silicone grease offers excellent water resistance, wide temperature stability, and compatibility with many rubber, plastic, and metal components. It is commonly used for lubricating and sealing O-rings, valves, and fittings, and for protecting electrical connections against moisture.
  • CTFE (Fluorolube) oils and greases are chemically inert lubricants engineered for demanding environments where standard hydrocarbon-based products fail. They resist strong oxidizers, acids, and aggressive chemicals, making them a preferred choice for oxygen service, chlorine and other reactive-gas handling, and corrosion-prone assemblies.

When selecting an industrial lubricant, consider operating temperature range, load and pressure, chemical exposure and compatibility, water and moisture resistance, viscosity requirements, and whether the product will contact rubber, plastic, or sensitive substrates.

PRODUCT GROUPING INTROS

Hydraulic Oil

Hydraulic oil products deliver reliable power transfer, wear protection, and oxidation resistance for pumps, valves, cylinders, and other hydraulic system components operating under pressure.

Silicone Greases

Silicone grease products provide dependable water resistance, wide-temperature stability, and material compatibility for lubricating and sealing O-rings, valves, fittings, and electrical connections.

CTFE (Fluorolube) Corrosion-Resistant Oils & Greases

CTFE (Fluorolube) oils and greases are chemically inert, nonflammable lubricants built for oxygen service, reactive-gas handling, and other aggressive-chemical environments where standard oils and greases break down.

FAQS

What is the difference between oil and grease?

Oil is a fluid lubricant that flows freely and is well suited to circulating systems, high speeds, and applications requiring cooling and continuous lubrication. Grease is a thickened lubricant that stays in place, resists leakage, and provides longer-lasting protection for bearings, fittings, and components that are difficult to relubricate frequently.

What is hydraulic oil used for?

Hydraulic oil is used to transmit power within hydraulic systems while lubricating and protecting pumps, valves, and cylinders. Selecting the correct viscosity grade and additive package helps maintain performance, control wear, and resist oxidation across varying temperatures and pressures.

What is silicone grease used for?

Silicone grease is commonly used to lubricate and seal O-rings, valves, and fittings, and to protect electrical connections from moisture. Its water resistance and broad temperature stability make it a versatile choice for many maintenance and assembly applications.

What are CTFE or Fluorolube oils and greases?

CTFE (Fluorolube) oils and greases are chemically inert, nonflammable lubricants based on chlorotrifluoroethylene. They are engineered for aggressive environments such as oxygen service and reactive-chemical handling, where conventional hydrocarbon-based lubricants can react or degrade.

Which lubricant offers the best chemical resistance?

For the most demanding chemical environments, CTFE (Fluorolube) oils and greases generally offer the highest resistance because they are chemically inert. The best choice still depends on the specific chemicals, temperatures, and materials involved, so reviewing the product specifications is recommended before selecting a solution.

Is silicone grease safe to use on rubber and plastic?

Silicone grease is compatible with many rubber and plastic components, which is one reason it is widely used on O-rings and seals. Compatibility can vary by material, so confirming the manufacturer specifications for your specific substrate is recommended before application.
