We offer a seal kit / repair kit for the top hydraulic cylinder A1298001672 / 1298001672 / 129 800 1672 used in Mercedes SL R129 (front lock cylinder) / E-Class W124 (rear bow lock cylinder) / CLK W208 (rear bow lock cylinder) models.  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 Polyurethane rod seals (usually green or blue) from China, most of which are of lower quality 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). HPU combines excellent mechanical properties with high chemical resistance, exceeding those of standard Polyurethane. Additionally, Viton® 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 and piston 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 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 Polyurethane rod seals (usually green or blue) from China, most of which are of lower quality 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). HPU combines excellent mechanical properties with high chemical resistance, exceeding those of standard Polyurethane. Additionally, Viton® 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 and piston 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.

We offer an extraction tool for the hydraulic line port seals used in Mercedes SL R129 models.  These seals are located within the hydraulic ports of the cylinders and the distributor (Mercedes part number A1298000022 / 1298000022) and consist of a uniquely shaped quad seal and a brass support ring to keep the seal in place. With this special extraction tool you can remove the brass ring. This extraction tool includes the following parts: 1 x special thread-forming screw, short - for the distributor and all hydraulic cylinders except A1298001772 / A1298001872 / A1248000272 (bow extension cylinders) 1 x special thread-forming screw, long - only needed for hydraulic cylinders A1298001772 / A1298001872 / A1248000272 (bow extension cylinders) 1 x spacer - only needed for hydraulic cylinders A1298001772 / A1298001872 / A1248000272 (bow extension cylinders) 1 x washer 2 x nut Brass ring removal instructions:- The distributor / all hydraulic cylinders except A1298001772 / A1298001872 / A1248000272 (bow extension cylinders): Remove the tension clips that hold the hydraulic lines in place and pull the hydraulic lines carefully out of the distributor/cylinder. Put the distributor/hydraulic cylinder in a vice with the hydraulic line port opening facing upwards. Now thread one of the nuts onto the short screw until it touches the screw head (some force may be needed at the beginning due to the unique shape of the threads). Place the washer on top of the hydraulic line port whose seal you would like to remove. Insert the screw through the washer into the brass ring using a Torx T20 screw driver. Proceed to turn the screw driver until the screw is fully seated inside the brass ring (the screw is fully seated either when the nut touches the washer or when the brass ring starts rotating). Now use one hand to hold the screw driver (and the screw) in place while turning the nut clockwise with a 7mm wrench. This will lift the brass ring slowly until it can be fully removed. After that, you can remove the brass ring from the screw by using a pair of pliers and holding onto the outside of the brass ring while unscrewing the screw. - Hydraulic cylinders A1298001772 / A1298001872 / A1248000272 (bow extension cylinders): Remove the tension clips that hold the hydraulic lines in place and pull the hydraulic lines carefully out of the cylinder. Put the hydraulic cylinder in a vice with the hydraulic line port opening facing upwards. Now thread one of the nuts onto the long screw until it touches the screw head (some force may be needed at the beginning due to the unique shape of the threads). Place the washer on top of the hydraulic line port whose seal you would like to remove (the lower hydraulic line port opening of the bow extension cylinders requires placing the included spacer on the lower shoulder to level the washer due to the two port openings being too close to each other). Insert the screw through the washer into the brass ring using a Torx T20 screw driver. Proceed to turn the screw driver until the screw is fully seated inside the brass ring (the screw is fully seated either when the nut touches the washer or when the brass ring starts rotating).
