- 3. Combination Metal-to-Oil Seal Combination seals combine the features of both face-type and cartridge-type seals. They consist of two metal rings that are pressed together, with a sealing element sandwiched between them. The outer ring of the seal is designed to fit into a groove in the housing, while the inner ring remains in contact with the rotating shaft. Combination seals are commonly used in applications where both high pressure and temperature conditions are present.
Depending on the application, premium lip materials may need to be used, such as Ethylene-acrylic (Varmac®). This material features good abrasion and dry running capabilities, higher heat capabilities than nitrile and polyacrylate, and better low-temperature performance than polyacrylate.
- 2. Aerospace industry High temperature rubber gaskets are used in aircraft engines, fuel systems, and air conditioning systems to ensure sealing under extreme conditions.
- Replacing the m20 valve cover gasket is a relatively simple task that can be done by experienced DIYers or a professional mechanic. The first step is to remove the valve cover, which is usually held in place by a series of bolts
