Oil seals are typically made of rubber or synthetic materials that are resistant to oil, heat, and pressure. They are designed to withstand the harsh conditions within an engine or machinery, such as high temperatures and varying levels of pressure. The seal is usually placed in a housing or a groove in order to effectively seal the gap between two moving parts.

In some cases, injectable medications may be used to treat ticks in cows. These medications are typically administered by a veterinarian and work by killing ticks either when they bite the cow or when they come into contact with the medication in the cow's blood. Injectable medications are often more potent than topical or oral treatments and can provide long-lasting protection against ticks.
