Is your hydraulic system leaking, making more noise, or generating more heat than usual? Hydraulic systems operate under high pressure, where worn seals, gaskets, pumps, control valves, packing glands, and piston rods can lead to oil leakage, reduced performance, and downtime.
Lindemann HYD-SL Stop Leak helps reduce leakage in hydraulic systems while improving the properties of the hydraulic oil. Its formula restores flexibility to synthetic rubber seals without swelling, while PTFE particles and protective additives reduce friction, wear, heat, and noise.
Lindemann HYD-SL Stop Leak is commonly used for:
When leakage is caused by worn seals, reduced seal flexibility, or hydraulic system wear, a dedicated hydraulic stop leak treatment can make a noticeable difference.
Lindemann HYD-SL Stop Leak is added directly to the hydraulic oil. Once circulated through the system, the seal-revitalising additives help restore flexibility to synthetic rubber seals without causing them to swell.
At the same time, PTFE particles and protective additives improve lubrication and reduce friction between moving parts. This helps reduce wear on pumps, control valves, packing glands, and piston rods, while also lowering heat and noise generation.
Lindemann HYD-SL Stop Leak is suitable for hydraulic systems where leakage reduction, improved lubrication, and extra protection are required. It is especially useful in demanding sectors such as marine, transport, and industry.
The product can be used in hydraulic systems with filters of 5 microns or larger. One 1 litre bottle is suitable for 50 litres of hydraulic oil.
Lindemann HYD-SL Stop Leak is intended for hydraulic systems and hydraulic oil applications. Do not use this product in hydraulic brake systems with brake fluid of vegetable origin.
Hydraulic leaks can lead to oil loss, reduced system pressure, increased wear, downtime, and expensive repairs. Treating the system early helps restore sealing performance and improves the lubricating properties of the hydraulic oil.
Lindemann HYD-SL Stop Leak is ideal for professional hydraulic systems where leakage reduction, smoother operation, lower wear, reduced heat, and improved reliability are required.

Usage
FAQ
In general, most additives on the additive market are fairly similar. The raw materials are the same in most products. The difference, however, lies in the ratio between the active chemical ingredients and the base ingredients such as oil and white petroleum.
The proportion of active ingredients in Lindemann additives is significantly higher than in most competing products. This results in a longer-lasting and more effective performance.
In addition, several specific Lindemann products have extra distinguishing properties.
Lindemann additives are often based on Teflon. Teflon has several beneficial properties.
When you use a Lindemann Teflon additive, resistance is significantly reduced. Especially during a cold start, Teflon creates much less friction than regular oil. The less resistance there is, the less energy is needed to keep the car running. Fuel savings are therefore one of the results.
In addition, Teflon settles into small cavities and scratches. This can help reduce oil consumption, for example. Teflon is also able to withstand extremely high pressure, helping to prevent wear at all times.
