Crush Washers vs Gaskets – What’s the Difference

Crush Washers vs Gaskets

When it comes to vehicle maintenance, every little detail counts. One of the smallest but most crucial components of your vehicle’s oil system is the seal between your filter and engine block. The two most commonly used seals are crush washers and gaskets. But which one is better? In this article, we’ll dive into the pros and cons of each so you can decide which is best for your vehicle.

What is Crush Washer?

A crush washer is a type of washer that is used to seal fluid or gas connections. The name “crush washer” comes from the fact that the washer is designed to be crushed when tightened, creating a tight seal. Crush washers are most commonly used in automotive and plumbing applications.

What is Gasket?

A gasket is a seal used to fill the space between two surfaces. Gaskets are typically made from rubber, cork, or paper. They are used in various automotive, plumbing, and electrical applications.

Difference Between Crush Washers and Gaskets

One advantage of crush washers is that they are easy to install. They can also be reused if they are not damaged during installation. Additionally, crush washers provide a good seal and are less likely to leak than other seals.

Advantages of Gaskets

One advantage of gaskets is that they can be made from various materials, including rubber, cork, and paper. This allows them to be customized for specific applications. Additionally, gaskets provide a better deal than crush washers and are less likely to leak.

Disadvantages of Crush Washers

One disadvantage of crush washers is that they can be difficult to remove once installed. Additionally, they can be damaged during installation, which may cause them to leak. Finally, crush washers provide less seal than gaskets and may not last as long.


While it may seem like a small detail, choosing the right seal for your vehicle’s oil system is crucial to prevent leaks and ensure proper engine function. Choosing a crush washer or gasket depends on your preference, the frequency of oil changes, and what your vehicle manufacturer recommends. As with any maintenance task, always refer to your owner’s manual and consult a mechanic if you have any questions.
