- Oil seals are typically made of a flexible material, such as rubber or silicone, that is designed to create a tight seal around a rotating shaft or axle. This seal prevents oil or other fluids from leaking out of the machine, which can cause damage and decrease efficiency. In addition to preventing leaks, oil seals also help to keep dirt, dust, and other contaminants from entering the machinery, which can cause wear and tear over time.
Another factor you need to consider is the type of lubricants that are more suitable for the seals. Check for the appropriate viscosity of the lubricant that’s compatible with the seal material.
Before installing the oil seal, it is essential that the oil seal, shaft and bore are not damaged. So, ensure that the surfaces the oil seal comes in contact with do not have any sharp points or burrs. The sealing lip is fragile, so any minor damage to it can cause leakage. Also, make sure the oil seal is clean. Even a small amount of dirt can cause a leak. Therefore, never use a pre-used oil seal for the assembly.
- A rubber locking gasket, derived from its name, is a specialized type of gasket designed with a unique locking mechanism. This mechanism allows it to securely fasten onto the connecting surfaces, preventing any leaks or unwanted intrusion. The locking feature is achieved through various methods, such as interlocking grooves, tabs, or even a snap-fit design, all tailored to enhance the gasket's holding power.

Clean all dirt and oil from the housing, and set the new seal in place with its open (spring) side towards the engine.
In this an auxiliary lip is provided along with the regular sealing lip. The additional dust lip protects the main sealing lip against dust and other fine solid contaminants and therefore this type is recommended for use in polluted environments. To achieve a long lifetime a suitable lubricant between the two sealing lips should be applied.

Proper care and maintenance of square rubber gaskets are essential to ensure their longevity and effectiveness. Regular inspection for signs of wear, damage, or degradation is important to prevent leaks and maintain the integrity of the seal. Replacing worn or damaged gaskets promptly can help prevent costly repairs and downtime.
