We offer a seal kit / repair kit for the top hydraulic cylinder A2318000372 / 2318000372 / 231 800 0372 (lock latch cylinder) used in Mercedes model SL R231. A lot of Mercedes convertible owners are aware of the well known problem: After a while the hydraulic cylinders responsible for opening and closing the soft top start leaking and do not work properly anymore.The leak occurs when the installed o-rings and rod seals wear out to a point that they are not able to withstand the pressure inside the hydraulic cylinder anymore. This is especially noticeable during the summer in warmer regions since the original materials are limited in terms of temperature resistance. For this reason we have the rod seals manufactured from affordable polyurethane (AU, red color) as well as heat and wear resistant Viton (FPM/FKM, brown color). Viton has the same mechanical properties as polyurethane, but has a far greater temperature resistance (from -20°C/-4°F to +204°C/+400°F) and is therefore the preferred material for vehicles in warmer regions. The rod seals are CNC-milled to our specification in Germany within tolerance class DIN ISO 2768-1-m to ensure a high level of accuracy. A hydraulic cylinder contains a rod seal, an o-ring (depending on the model, not always installed) and a one- or two-piece piston seal (depending on the model). If the hydraulic cylinder is leaking, you'll need to replace the rod seal. If the hydraulic cylinder is not able to open and close the soft top properly anymore, you'll need to replace the piston seal.Attention: Although the seals we offer have a high temperature range, they may only be used with the following types of hydraulic fluid to ensure smooth operation and a long service life:- Genuine Mercedes Benz hydraulic fluid MB 343.0, hydraulic fluids in accordance with standard DIN 51 524, HLP 32 or standard ISO 11158, HM 32
