This comprehensive set of\u00a016<\/strong>\u00a0U cup seals & 14 O-ring seals<\/strong>\u00a0is what you need to rebuild all 11 (or 12, depending on year) of your car roof’s hydraulic cylinders. Because of changes made by Mercedes during the R129 chassis’ run, We have included all the seals needed regardless of year or model.<\/p>\n

This is an upgrade to the\u00a0OEM U Cup Seals<\/strong>, which are not capable of withstanding the aggressive\/corrosive hydraulic fluids.<\/p>\n

The\u00a0Enhanced Urethane<\/strong>\u00a0compound used in these U cup seals is exceptionally resistant to petroleum based oils, found in hydraulic fluids used in the Mercedes Benz\u00a0convertible top hydraulic system.<\/p>\n

Fits the following vehicles built on the Mercedes SL Class Convertible R129 chassis:<\/p>\n
