We offer a seal kit / repair kit for the top hydraulic cylinder A1298001672 / 1298001672 / 129 800 1672 used in Mercedes models SL R129 (front lock cylinder) / E-Class W124 (rear bow lock cylinder) / CLK W208 (rear bow lock cylinder).  The issue: 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, rod seals and piston 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. What others offer: Most competitors source cheap, low-quality polyurethane rod seals (usually green or blue) from China, most of which are even lower-grade than the original rod seals which were already limited in terms of service life and heat resistance. Our solution: We wanted more than just a simple and cheap replacement but a solution that incorporated unparalleled longevity and durability. Therefore we developed two kinds of rod seals made from high-tech materials: High-Performance Polyurethane (HPU, red color) as well as heat and wear resistant Viton® (FPM/FKM, brown color). Viton has the same mechanical properties as our High-Performance 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 specifications within tolerance class DIN ISO 2768-1-f (fine) in Germany to ensure a high level of accuracy. Seal types: 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. If the hydraulic cylinder is leaking, you'll need to replace the rod seal (and the o-ring). 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

We offer a complete rod seal kit / repair kit for the top hydraulic cylinders used in Mercedes SL R129 models.  This seal kit contains parts to replace the rod seals of the following hydraulic cylinders:2 x A 129 800 1672 (front lock cylinder)2 x A 129 800 2172 (rear lock cylinder)2 x A 129 800 2072 (tonneau cover lift cylinder)4 x A 129 800 0072 (tonneau cover lock cylinder, includes two additional A 129 800 0072 seal kits, only used in certain models)2 x A 129 800 0272 (main lift cylinder)2 x A 129 800 1772 / A 129 800 1872 / A 124 800 0272 (bow extension cylinder) The issue: 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, rod seals and piston 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. What others offer: Most competitors source cheap, low-quality polyurethane rod seals (usually green or blue) from China, most of which are even lower-grade than the original rod seals which were already limited in terms of service life and heat resistance. Our solution: We wanted more than just a simple and cheap replacement but a solution that incorporated unparalleled longevity and durability. Therefore we developed two kinds of rod seals made from high-tech materials: High-Performance Polyurethane (HPU, red color) as well as heat and wear resistant Viton® (FPM/FKM, brown color). Viton has the same mechanical properties as our High-Performance 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 specifications within tolerance class DIN ISO 2768-1-f (fine) in Germany to ensure a high level of accuracy. Seal types: 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. If the hydraulic cylinder is leaking, you'll need to replace the rod seal (and the o-ring). If the hydraulic cylinder is not able to open and close the soft top properly anymore, you'll need to replace the piston seal.
