Today we’re going to talk about lubrication of O-rings. Lubrication of O-rings is extremely important. The greatest benefit of using a lubricant is typically obtained during installation. Using a lubricant is going to decrease the surface friction of the O-ring helping to prevent abrasion, pinching or cutting of the O-ring during installation. Lubricating an O-ring can also help to seat the O-ring properly into the application, as well as aid and speed up automated assembly processes.
The proper method of applying a lubricant to an O-ring always seems to be an area of concern for many of our customers and there are many methods used in the marketplace.
- One is to apply the lubricant to the O-ring using your fingers, your hand or a brush.
- Another is to dip the O-ring into a container of the lubricant.
- A third method commonly used is to dispense the O-ring lubricant into the seal packaging and use what we call the “shake and bake” method.
The common goal of all of these different lubrication methods is to have a thin uniform film applied to the entire surface of the O-ring when completed. This will ease installation and provide best friction reduction.
