Door Closer Damping Fluid

Overview

  • Lube-V Synthetic Blend Hydraulic Door Closer Damping Fluid is a customized product, specially designed to provide ultimate shock absorbing performance for hydraulic door damping system.

  • Other than door closer damping system, Lube-V Hydraulic Door Closer Damping Fluid can also be used as a shock oil for suspension and other systems.

  • For maximum shock dampening performance, Lube-V proprietary formula has a very high viscosity index (VI), much much higher than regular hydraulic fluids and jack oils, and even higher than most synthetic fluids. Lube-V Hydraulic Door Closer Damping Fluid also includes advanced shock absorbing ingredients that are commonly used in aircraft landing gear and shock fluid. (Refer to our “FAQ” section for more details)

  • Shock Absorption: Provide consistent and excellent damping/shock absorbing under most severe temperature conditions by integrating most advanced ingredients including aircraft shock absorbing agents in the formula. 

  • Resistance to Temperature Fluctuations: Minimize the effect of seasonal adjustments and temperature fluctuation. Offer smooth operation over a wide range of temperatures in all climate conditions. (Refer to our “FAQ” section for more details.)

  • Protection: Protect metal parts of equipment against scuffing, rust and corrosion for long-term durability.

Performance Data

  • Outstanding performance much better than regular hydraulic fluids (for example, jack oils).

Frequently Asked Questions (FAQ)

1. What is difference between Lube-V Hydraulic Door Closer Damping Fluid and other hydraulic fluids such as jack oils? How is it related to the application in door damping system? 

For door damping system, shock absorption capability is the most important property. For a damping fluid to perform the best shock absorption performance, high viscosity index (VI) is preferred. The higher the VI is, the better the shock absorbing performance of a fluid is. (Please refer to our “Advantages and Technical Specifications” section for more details about VI.)

A regular hydraulic fluid (e.g. jack oil), whether or not it is full synthetic, usually has very low viscosity index (VI) value, typically around 100. By integrating the advanced aircraft landing shock absorbing technology,  Lube-V Hydraulic Door Closer Damping Fluid is specially designed to be used in door damping application with VI value of 360, which is usually over 250 higher than regular hydraulic fluids, indicating its outstanding shock absorbing performance.

 

2. Can Lube-V Door Closer Damping Fluid be used as a shock oil or suspension fluid? 

Yes. With its extremely high VI and advanced aircraft landing shock absorbing ingredient(s), Lube-V Door Closer Damping Fluid works perfectly as a shock oil or suspension fluid.

 

3. Can Lube-V Door Closer Damping Fluid be used in all climate conditions? 

Yes. One of the great advantages of Lube-V Suspension Fluid is that it is not only suitable for use in all climate conditions with a very low pour point, but also can be used for large temperature fluctuations during the day.  

Right viscosity is very important for the fluid to perform the proper function. However, viscosity of any fluid including door closer damping fluid will change with the temperature. It will damage your system if viscosity becomes too high (when temperature is low) or too low (when temperature is high).Viscosity Index (VI) is a good measure of this viscosity change with temperature. The higher VI, the less viscosity change with temperature, the better the fluid is.

Lube-V Hydraulic Door Closer Damping Fluid has a pour point of -76°F, indicating the fluid is still able to flow and perform the proper function even at very low ambient temperature. More importantly, it is specially formulated to greatly minimize the extent of viscosity change during temperature fluctuation. In more technical words, Lube-V Hydraulic Door Closer Damping Fluid has a very high VI, and hence, it has excellent resistance of fluid viscosity to temperature fluctuations.
