Important Functions of Oil Seals and Their Types, Let's Take a Look!

The oil seal functions to protect the engine lubricant so that it remains in the car engine and is not contaminated with dirt. This way, the engine is free from dirt that triggers wear on the engine components. Given the important function of the oil seal on the performance of engine components, the condition of the oil seal must always be monitored.

In addition to what has been explained earlier, the oil seal has other functions and is divided into several types. For more details, please refer to the following discussion.

Function of Oil Seal

Behind its small and compact size, the oil seal actually holds various benefits for the continuity of the car engine. Here are the complete functions of the oil seal.

1. Protecting the engine from contamination by dirt

The main function of the oil seal is to protect the engine from contamination by all types of dirt and other materials. This includes dust, water, and substances with acidic or basic concentrations. As is known, the oil seal is designed in a mini shape and serves as a tight cover. This design makes it difficult for dirt or other materials to enter when used to close the lubricant tank.

2. Preventing lubricant or oil leakage

The next function is to prevent lubricant or oil leakage. When the oil seal is used to close, the lubricant or engine oil is kept inside the engine.

3. Extending the lifespan of engine components

In addition, the oil seal also functions to extend the lifespan of engine components. Why is that? Because the lubricant or oil in the engine does not leak and optimally lubricates all engine components. This lubrication prevents excessive friction between engine components. Excessive friction between engine components certainly accelerates the wear and tear of the engine.

Types of Oil Seals

Oil seals are divided into several types as follows.

1. O-ring

This type of oil seal has a ring shape as its name suggests. This type is made from plastic, synthetic rubber, or even natural materials. The O-ring shape, which resembles a ring with a perfect circle, makes it suitable for static seals because it can connect the engine and pipes.

2. Lip seal

Lip seals, also known as dynamic seals, function to tighten moving components. This way, lubricants and fluids in the engine will not mix. Additionally, lip seals help prevent engine components from wearing out quickly. Lip seals themselves are divided into several types based on their shape, including dual lip, single lip spring-loaded, double lip, and single lip.

3. Duo cone seal

The duo cone seal has a function similar to the lip seal, which is to prevent the mixing of lubricants and fluids. Additionally, the duo cone also prevents engine oil leakage. In terms of shape, the duo cone seal is designed like an ice cream cone but with a double cone. The material is made of rubber and is fitted into a groove metal retaining ring. This design helps prevent bending, is rust-resistant, can withstand heavy loads, and allows for simple maintenance.

4. Gasket

Gasket seals function as a lining for connections between parts, such as the engine and pipes. For the gasket seal to function properly, it must be made from metal and non-metal materials. The metal materials used come from aluminum, brass, and even copper.

Meanwhile, the non-metal materials used come from special paper, cork, rubber, and other materials. To prevent leakage between parts, the gasket seal must be installed on two surfaces of fluid-pressurized objects, or even more.

Thus, this is a complete discussion about the functions and types of car oil seals. After reading the above review, I hope you always pay attention to the condition of the oil seal. If it is damaged, immediately replace it at the nearest Daihatsu workshop to obtain genuine spare parts.
