Hi Tomek, we have in stock for pre-face Tesla S rear, the sealing rings. But the o-ring we only sell as a set together with the 'support- and stop ring'. You can see her: www.teslasuspension.com/p/sealing-rings-tesla-s-air-strut-rear/ For the Tesla X, we most likely get the O-rings for the top cover in stock by end of the month
