- Benefits of Using Lip Seal Gaskets
2, oil seal lightweight, fewer supplies. Each type of oil seal is a combination of thin-walled metal parts and rubber parts, and its material consumption is very small so that each oil seal has a lightweight.
- The valve cover gasket is a seal placed between the valve cover and the engine cylinder head. Its primary function is to prevent oil from entering the spark plug wells while containing pressure within the engine. A 4.0 valve cover gasket refers to a specific type or model designed for engines with a particular configuration or size, suggesting it is tailored for optimal performance in such systems.
What Is an Oil Seal?
Other important factors are ensuring the hardness and roughness of the shaft are correct. A shaft hardness of HRC 45 is recommended for a rubber sealing lip, with a roughness of Ra 0.4-0.8. A higher shaft hardness of HRC 60 and shaft roughness of Ra 0.1-0.4 is recommended for a PTFE lip.
