Lindemann HYD-SL Stop Leak – Reduces leakage in hydraulic systems

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.

What problems is this suitable for?

Lindemann HYD-SL Stop Leak is commonly used for:

  • Leakage in hydraulic systems
  • Worn or hardened synthetic rubber seals
  • Leakage around packing glands and piston rods
  • Wear on pumps, control valves, and moving components
  • Heat, noise, downtime, and repair costs caused by hydraulic leaks

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.

How does it work?

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.

Suitable for hydraulic systems

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.

Important compatibility information

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.

Reduce leakage, wear, heat, and downtime

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.
