Seal Kits


Tried-and-true excavator cylinder seal kits

Whether it’s about trench digging, forestry work, landscaping, or some other excavator application, high levels of humidity are not something you can avoid on site. What makes the operation even more complicated is that there is always a risk of fluid leakage in a hydraulic cylinder. And if it is not prevented on time, your construction project is likely to be put in jeopardy, leading to millions of dollars in expenses. To protect yourself from dangers of that kind, you have to make sure all parts of your heavy equipment are in perfect condition while replacing those which bear signs of deterioration. This is when you need Fridayparts and its range of excavator cylinder seal kits. Moreover, in our store you can find travel motor seal kits as well as control level seal kits.

Our store is all about carefully tested replacement parts for heavy equipment and vehicles. We offer thousands of quality items which are designed to last for years.

Major signs of cylinder seal kit deterioration

So, how to minimize the risk of fluid damages and find out that your seal material is in poor condition? Take a look at some signs that will help you with that:

  • loss of elasticity that makes the material easy to crumble;
  • profile extrusion;
  • excessive grooves, cuts, or scratches;
  • burned surface or a missing side of the seal;
  • long splits and cracks;
  • material hardening, swelling, or glazing;
  • dented lip of the seal;
  • excessive wear and tear of the surface.

There are many causes of cylinder seal failures. And most of them are inevitable because of the conditions of the operation environment, like continuous exposure to sunlight or extreme heat generated by heavy-duty vehicles. That said, the only way to ensure the smooth operation is to carry out regular maintenance and replace damaged parts immediately.
