Dichtungen
Gaskets and sealing parts create tight, leak-free joints between the components of a commercial vehicle, keeping fluids and gases where they belong. This category covers gaskets, seals, O-rings, and related sealing parts used throughout the engine and other systems.
A gasket or seal sits between two parts and fills the tiny gaps at their joint, so oil, coolant, fuel, air, or exhaust cannot leak out or contaminants get in. They hold pressure where it is needed, such as in the engine, and keep each system sealed so it can do its job. Many are designed for the specific temperatures, pressures, and fluids of their location.
Gaskets and seals harden, crack, or fail with heat, pressure, age, and chemical exposure. Signs include oil, coolant, or fuel leaks, loss of pressure, and contamination. Because a failed gasket such as a blown head gasket can cause serious problems, leaks are traced and the gasket or seal replaced, with the mating surfaces cleaned and the correct part fitted to specification.
The correct gasket or seal depends on the vehicle and engine model, its location, and the material and dimensions. Confirm the part against the vehicle specification before fitting.
Frequently asked questions
What do gaskets and seals do?
They create tight, leak-free joints between parts, keeping oil, coolant, fuel, air, or exhaust where it belongs and contaminants out.
What are the signs of a failed gasket or seal?
Oil, coolant, or fuel leaks, a loss of pressure, and contamination. A serious case such as a blown head gasket can cause major engine problems.
Why do gaskets and seals wear out?
Heat, pressure, age, and exposure to fluids harden and crack them over time, so they eventually need replacing.
How do I choose the right gasket or seal?
Match it to the vehicle and engine model, its location, and the material and dimensions, and confirm against the vehicle specification before fitting.
