Low Maintenance: Unlike other types of springs, gas springs require little or no maintenance. They still consist of multiple parts. Gas springs have a piston, seals and attachments. However, these parts are enclosed in a cylinder, so maintaining gas springs is a breeze. You don’t have to worry about cleaning the parts, nor do you have to worry about oiling or lubricating them. With their self-enclosed design, gas springs are easy to maintain.http://www.liftgasspring.com/gas-spring/
