Today the modern design of the office chairs has eliminated the carter cover and the gas piston is exposed. The normal gas pistons generally have only black, white or chromed tube, with the ring closing the stem black, and the extensible stem brushed. The extensible stem then gets dirty with lubrication grease. With Clean Cylinder you can avoid all this, because the pistons are all black, white or chrome, both the tube, the ring that the extensible stem, and there is no leakage of grease in the extensible stem avoiding unsightly signs and possible sources of stains.
